Editor) +===== + +(This doc started Dec 2009 by dgreenspan.) + +ACE2 is EtherPad's editor, a content-editable-based rich text editor +that supports IE6+, FF(2?/)3+, Safari(3?/)4+. It supports +collaborative editing using operation transforms (easysync2), +undo/redo, copy/paste. + +The name "ACE2" is because this is a rewrite of aiba's original +content-editable AppJet Code Editor. + +== Building it + +In this directory, run `bin/make normal etherpad` (requires scala), +which generates `build/ace2.js` and copies this and other files into +the etherpad source tree. To have the script keep running and +automatically rebuild when source files change, run `bin/make auto +etherpad`. + +The original reason for the build process was that ACE needs to +construct two nested iframes on the client, and to do this without +incurring round-trips to the server, it programmatically loads code +into the outer iframe that loads code into the inner iframe; so the +bulk of ACE's code is compressed into a string literal (twice). Later +on, refactoring meant that the source is also divided into more than a +dozen files that the build script combines, and some are also +server-side EtherPad modules or client-side libraries (or both). + +The master copy of the operational transform (OT) library, easysync2, +lives here. + +In the early days it was possible to run ACE in a sort of development +mode, without the compression and iframe injection, by running it out +of the 'www' directory, but this is no longer possible. + +== Browser support + +We went out of our way to support IE6+. IE's design-mode is quite +robust, though there are some differences in manipulation of the +selection and insertion point and in the DOM representation we had to +use. + +We don't support Opera. Opera is a problematic case, because +apparently JS running in different iframes is run concurrently, not +linearized into a single event thread. This seems to be a rather +obscure fact and is almost difficult to believe. As if iframes don't +complicate scripting enough! + +== Syntax highlighting + +Though syntax highlighting predated rich text as the original +motivation for the design of ACE, support was eventually dropped in +EtherPad. At first the plan was to generalize it to other programming +languages, but the task was deprioritized (and difficult), and during +subsequent optimization and refactoring of ACE, calls to the +incremental lexer were stripped out because they complicated things. + +One plan for multi-language syntax highlighting, never implemented, +was to calculate syntax highlighting on the server as a sort of "style +overlay" and feed updates to the client along with updates to the +document text. + +== Changeset format + +See easysync-notes.txt for some notes on the changeset format, which +was redesigned with the advent of rich text. diff --git a/infrastructure/ace/bin/make b/infrastructure/ace/bin/make new file mode 100755 index 0000000..dad11ff --- /dev/null +++ b/infrastructure/ace/bin/make @@ -0,0 +1,337 @@ +#!/bin/sh +exec scala -classpath lib/yuicompressor-2.4-appjet.jar:lib/rhino-js-1.7r1.jar $0 $@ +!# + +import java.io._;

+How This API Document Is Organized

+
+This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.

+Overview

+
+ +

+The Overview page is the front page of this API document and provides a list of all packages with a summary for each. This page can also contain an overall description of the set of packages.

+

+Package

+
+ +

+Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain four categories:

    +
  • Interfaces (italic)
  • Classes
  • Enums
  • Exceptions
  • Errors
  • Annotation Types
+
+

+Class/Interface

+
+ +

+Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:

    +
  • Class inheritance diagram
  • Direct Subclasses
  • All Known Subinterfaces
  • All Known Implementing Classes
  • Class/interface declaration
  • Class/interface description +

    +

  • Nested Class Summary
  • Field Summary
  • Constructor Summary
  • Method Summary +

    +

  • Field Detail
  • Constructor Detail
  • Method Detail
+Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.
+ +

+Annotation Type

+
+ +

+Each annotation type has its own separate page with the following sections:

    +
  • Annotation Type declaration
  • Annotation Type description
  • Required Element Summary
  • Optional Element Summary
  • Element Detail
+
+ +

+Enum

+
+ +

+Each enum has its own separate page with the following sections:

    +
  • Enum declaration
  • Enum description
  • Enum Constant Summary
  • Enum Constant Detail
+
+

+Tree (Class Hierarchy)

+
+There is a Class Hierarchy page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with java.lang.Object. The interfaces do not inherit from java.lang.Object.
    +
  • When viewing the Overview page, clicking on "Tree" displays the hierarchy for all packages.
  • When viewing a particular package, class or interface page, clicking "Tree" displays the hierarchy for only that package.
+
+

+Deprecated API

+
+The Deprecated API page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.
+

+Index

+
+The Index contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.
+

+Prev/Next

+These links take you to the next or previous class, interface, package, or related page.

+Frames/No Frames

+These links show and hide the HTML frames. All pages are available with or without frames. +

+

+Serialized Form

+Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking "Serialized Form" in the "See also" section of the class description. +

+

+Constant Field Values

+The Constant Field Values page lists the static final fields and their values. +

+ + +This help file applies to API documentation generated using the standard doclet. + +

+Method Detail
+ +

+get

+
+public static ClassCache get(Scriptable scope)
+
+
Search for ClassCache object in the given scope. + The method first calls + ScriptableObject.getTopLevelScope(Scriptable scope) + to get the top most scope and then tries to locate associated + ClassCache object in the prototype chain of the top scope. +

+

+
Parameters:
scope - scope to search for ClassCache object. +
Returns:
previously associated ClassCache object or a new instance of + ClassCache if no ClassCache object was found.

associate(ScriptableObject topScope)
+
+
+
+ +

+associate

+
+public boolean associate(ScriptableObject topScope)
+
+
Associate ClassCache object with the given top-level scope. + The ClassCache object can only be associated with the given scope once. +

+

+
Parameters:
topScope - scope to associate this ClassCache object with. +
Returns:
true if no previous ClassCache objects were embedded into + the scope and this ClassCache were successfully associated + or false otherwise.

+ +

+setCachingEnabled

+
+public void setCachingEnabled(boolean enabled)
+
+
Set whether to cache some values. +

+ By default, the engine will cache the results of + Class.getMethods() and similar calls. + This can speed execution dramatically, but increases the memory + footprint. Also, with caching enabled, references may be held to + objects past the lifetime of any real usage. +

+ If caching is enabled and this method is called with a + false argument, the caches will be emptied. +

+ Caching is enabled by default. +

+

+visibleToScripts

+
+boolean visibleToScripts(java.lang.String fullClassName)
+
+
Return true iff the Java class with the given name should be exposed + to scripts. +

+ An embedding may filter which Java classes are exposed through + LiveConnect to JavaScript scripts. +

+ Due to the fact that there is no package reflection in Java, + this method will also be called with package names. There + is no way for Rhino to tell if "Packages.a.b" is a package name + or a class that doesn't exist. What Rhino does is attempt + to load each segment of "Packages.a.b.c": It first attempts to + load class "a", then attempts to load class "a.b", then + finally attempts to load class "a.b.c". On a Rhino installation + without any ClassShutter set, and without any of the + above classes, the expression "Packages.a.b.c" will result in + a [JavaPackage a.b.c] and not an error. +

+ With ClassShutter supplied, Rhino will first call + visibleToScripts before attempting to look up the class name. If + visibleToScripts returns false, the class name lookup is not + performed and subsequent Rhino execution assumes the class is + not present. So for "java.lang.System.out.println" the lookup + of "java.lang.System" is skipped and thus Rhino assumes that + "java.lang.System" doesn't exist. So then for "java.lang.System.out", + Rhino attempts to load the class "java.lang.System.out" because + it assumes that "java.lang.System" is a package name. +

+

+

+
Parameters:
fullClassName - the full name of the class (including the package + name, with '.' as a delimiter). For example the + standard string class is "java.lang.String" +
Returns:
whether or not to reveal this class to scripts

+
Turn on or off generation of code with callbacks to + track the count of executed instructions. + Currently only affects JVM byte code generation: this slows down the + generated code, but code generated without the callbacks will not + be counted toward instruction thresholds. Rhino's interpretive + mode does instruction counting without inserting callbacks, so + there is no requirement to compile code differently. +

+

+
Parameters:
generateObserverCount - if true, generated code will contain + calls to accumulate an estimate of the instructions executed.

+
+
Control if toString() should returns the same result + as toSource() when applied to objects and arrays. + If hasFeature(FEATURE_TO_STRING_AS_SOURCE) returns true, + calling toString() on JS objects gives the same result as + calling toSource(). That is it returns JS source with code + to create an object with all enumeratable fields of the original object + instead of printing [object result of + Scriptable.getClassName()]. +

+ By default hasFeature(int) returns true only if + the current JS version is set to VERSION_1_2. +

+
+
Control if properties __proto__ and __parent__ + are treated specially. + If hasFeature(FEATURE_PARENT_PROTO_PROPERTIES) returns true, + treat __parent__ and __proto__ as special properties. +

+ The properties allow to query and set scope and prototype chains for the + objects. The special meaning of the properties is available + only when they are used as the right hand side of the dot operator. + For example, while x.__proto__ = y changes the prototype + chain of the object x to point to y, + x["__proto__"] = y simply assigns a new value to the property + __proto__ in x even when the feature is on. + + By default hasFeature(int) returns true. +

+FEATURE_DYNAMIC_SCOPE

+
+public static final int FEATURE_DYNAMIC_SCOPE
+
+
Control if dynamic scope should be used for name access. + If hasFeature(FEATURE_DYNAMIC_SCOPE) returns true, then the name lookup + during name resolution will use the top scope of the script or function + which is at the top of JS execution stack instead of the top scope of the + script or function from the current stack frame if the top scope of + the top stack frame contains the top scope of the current stack frame + on its prototype chain. +

+ This is useful to define shared scope containing functions that can + be called from scripts and functions using private scopes. +

+ By default hasFeature(int) returns false. +

+FEATURE_STRICT_VARS

+
+public static final int FEATURE_STRICT_VARS
+
+
Control if strict variable mode is enabled. + When the feature is on Rhino reports runtime errors if assignment + to a global variable that does not exist is executed. When the feature + is off such assignments creates new variable in the global scope as + required by ECMA 262. +

+ By default hasFeature(int) returns false. +

+FEATURE_STRICT_EVAL

+
+public static final int FEATURE_STRICT_EVAL

+
Control if strict eval mode is enabled. + When the feature is on Rhino reports runtime errors if non-string + argument is passed to the eval function. When the feature is off + eval simply return non-string argument as is without performing any + evaluation as required by ECMA 262. +

+ By default hasFeature(int) returns false. +

+

+
See Also:
Constant Field Values
+

+FEATURE_LOCATION_INFORMATION_IN_ERROR

+
+public static final int FEATURE_LOCATION_INFORMATION_IN_ERROR
+
+
When the feature is on Rhino will add a "fileName" and "lineNumber" + properties to Error objects automatically. When the feature is off, you + have to explicitly pass them as the second and third argument to the + Error constructor. Note that neither behaviour is fully ECMA 262 + compliant (as 262 doesn't specify a three-arg constructor), but keeping + the feature off results in Error objects that don't have + additional non-ECMA properties when constructed using the ECMA-defined + single-arg constructor and is thus desirable if a stricter ECMA + compliance is desired, specifically adherence to the point 15.11.5. of + the standard. +

+ By default hasFeature(int) returns false. +

+ + This method must be called to initialize a scope before scripts + can be evaluated in that scope.

+ + This method does not affect the Context it is called upon.

+ + This form of the method also allows for creating "sealed" standard + objects. An object that is sealed cannot have properties added, changed, + or removed. This is useful to create a "superglobal" that can be shared + among several top-level objects. Note that sealing is not allowed in + the current ECMA/ISO language specification, but is likely for + the next version. +

+

+
Parameters:
scope - the scope to initialize, or null, in which case a new + object will be created to serve as the scope
sealed - whether or not to create sealed standard objects that + cannot be modified. +
Returns:
the initialized scope. The method returns the value of the scope + argument if it is not null or newly allocated scope object.

+ If the object defines a length property convertible to double number, + then the number is converted Uint32 value as defined in Ecma 9.6 + and Java array of that size is allocated. + The array is initialized with the values obtained by + calling get() on object for each value of i in [0,length-1]. If + there is not a defined value for a property the Undefined value + is used to initialize the corresponding element in the array. The + Java array is then returned. + If the object doesn't define a length property or it is not a number, + empty array is returned. +

+

+
Parameters:
object - the JavaScript array or array-like object +
Returns:
a Java array of objects

+                                        Scriptable scope)
+
+
Convenient method to convert java value to its closest representation + in JavaScript. +

+ If value is an instance of String, Number, Boolean, Function or + Scriptable, it is returned as it and will be treated as the corresponding + JavaScript type of string, number, boolean, function and object. +

+ Note that for Number instances during any arithmetic operation in + JavaScript the engine will always use the result of + Number.doubleValue() resulting in a precision loss if + the number can not fit into double. +

+ If value is an instance of Character, it will be converted to string of + length 1 and its JavaScript type will be string. +

+ The rest of values will be wrapped as LiveConnect objects + by calling WrapFactory.wrap(Context cx, Scriptable scope, + Object obj, Class staticType) as in: +

+    Context cx = Context.getCurrentContext();
+    return cx.getWrapFactory().wrap(cx, scope, value, null);
+ 
+

+

+
Parameters:
value - any Java object
scope - top scope object +
Returns:
value suitable to pass to any API that takes JavaScript values.

Set the current optimization level. +

+ The optimization level is expected to be an integer between -1 and + 9. Any negative values will be interpreted as -1, and any values + greater than 9 will be interpreted as 9. + An optimization level of -1 indicates that interpretive mode will + always be used.

+public final int getMaximumInterpreterStackDepth()
+
+
Returns the maximum stack depth (in terms of number of call frames) + allowed in a single invocation of interpreter. If the set depth would be + exceeded, the interpreter will throw an EvaluatorException in the script. + Defaults to Integer.MAX_VALUE. The setting only has effect for + interpreted functions (those compiled with optimization level set to -1). + As the interpreter doesn't use the Java stack but rather manages its own + stack in the heap memory, a runaway recursion in interpreted code would + eventually consume all available memory and cause OutOfMemoryError + instead of a StackOverflowError limited to only a single thread.

+getInstructionObserverThreshold

+
+public final int getInstructionObserverThreshold()
+
+
Get threshold of executed instructions counter that triggers call to + observeInstructionCount(). + When the threshold is zero, instruction counting is disabled, + otherwise each time the run-time executes at least the threshold value + of script instructions, observeInstructionCount() will + be called. +

+

+
+
+
+
+ +

+setInstructionObserverThreshold

+
+public final void setInstructionObserverThreshold(int threshold)
+
+
Set threshold of executed instructions counter that triggers call to + observeInstructionCount(). + When the threshold is zero, instruction counting is disabled, + otherwise each time the run-time executes at least the threshold value + of script instructions, observeInstructionCount() will + be called.

+ Note that the meaning of "instruction" is not guaranteed to be + consistent between compiled and interpretive modes: executing a given + script or function in the different modes will result in different + instruction counts against the threshold. + setGenerateObserverCount(boolean) is called with true if + threshold is greater than zero, false otherwise. +

+

+
Parameters:
threshold - The instruction threshold
+
+
+
+ +

+setGenerateObserverCount

+
+public void setGenerateObserverCount(boolean generateObserverCount)
+
+
Turn on or off generation of code with callbacks to + track the count of executed instructions. + Currently only affects JVM byte code generation: this slows down the + generated code, but code generated without the callbacks will not + be counted toward instruction thresholds. Rhino's interpretive + mode does instruction counting without inserting callbacks, so + there is no requirement to compile code differently. +

+

+
Parameters:
generateObserverCount - if true, generated code will contain + calls to accumulate an estimate of the instructions executed.
+
+
+
+ +

+observeInstructionCount

+
+protected void observeInstructionCount(int instructionCount)
+
+
Allow application to monitor counter of executed script instructions + in Context subclasses. + Run-time calls this when instruction counting is enabled and the counter + reaches limit set by setInstructionObserverThreshold(). + The method is useful to observe long running scripts and if necessary + to terminate them. +

+ The instruction counting support is available only for interpreted + scripts generated when the optimization level is set to -1. +

+ The default implementation calls + ContextFactory.observeInstructionCount(Context cx, + int instructionCount) + that allows to customize Context behavior without introducing + Context subclasses. +

+

+
Parameters:
instructionCount - amount of script instruction executed since + last call to observeInstructionCount +
Throws: +

public class ContextFactory
extends java.lang.Object
+ + +

+Factory class that Rhino runtime uses to create new Context + instances. A ContextFactory can also notify listeners + about context creation and release. +

+ When the Rhino runtime needs to create new Context instance during + execution of Context.enter() or Context, it will call + makeContext() of the current global ContextFactory. + See getGlobal() and initGlobal(ContextFactory). +

+ It is also possible to use explicit ContextFactory instances for Context + creation. This is useful to have a set of independent Rhino runtime + instances under single JVM. See call(ContextAction). +

+ The following example demonstrates Context customization to terminate + scripts running more then 10 seconds and to provide better compatibility + with JavaScript code using MSIE-specific features. +

+
+public static ContextFactory getGlobal()
+
+
Get global ContextFactory. +

+

+
See Also:
hasExplicitGlobal(), +initGlobal(ContextFactory)
+
+
+
+ +

+hasExplicitGlobal

+
+public static boolean hasExplicitGlobal()
+
+
Check if global factory was set. + Return true to indicate that initGlobal(ContextFactory) was + already called and false to indicate that the global factory was not + explicitly set. +

+

+
See Also:
getGlobal(), +initGlobal(ContextFactory)
+
+
+
+ +

+initGlobal

+
+public static void initGlobal(ContextFactory factory)
+
+
Set global ContextFactory. + The method can only be called once. +

+

+
See Also:
getGlobal(), +hasExplicitGlobal()
+
+
+
+ +

+makeContext

+
+protected Context makeContext()
+
+
Create new Context instance to be associated with the current + thread. + This is a callback method used by Rhino to create Context + instance when it is necessary to associate one with the current + execution thread. makeContext() is allowed to call + Context.seal(Object) on the result to prevent + Context changes by hostile scripts or applets. +

+

+
+
+
+
+ +

+hasFeature

+
+protected boolean hasFeature(Context cx,
+                             int featureIndex)
+
+
Implementation of Context.hasFeature(int featureIndex). + This can be used to customize Context without introducing + additional subclasses. +

+

+
+
+
+
+ +

+getE4xImplementationFactory

+
+protected org.mozilla.javascript.xml.XMLLib.Factory getE4xImplementationFactory()
+
+
Provides a default + XMLLib.Factory + to be used by the Context instances produced by this + factory. See Context.getE4xImplementationFactory() for details. + + May return null, in which case E4X functionality is not supported in + Rhino. + + The default implementation now prefers the DOM3 E4X implementation. +

+

+
+
+
+
+ +

+createClassLoader

+
+protected GeneratedClassLoader createClassLoader(java.lang.ClassLoader parent)
+
+
Create class loader for generated classes. + This method creates an instance of the default implementation + of GeneratedClassLoader. Rhino uses this interface to load + generated JVM classes when no SecurityController + is installed. + Application can override the method to provide custom class loading. +

+

+
+
+
+
+ +

+getApplicationClassLoader

+
+public final java.lang.ClassLoader getApplicationClassLoader()
+
+
Get ClassLoader to use when searching for Java classes. + Unless it was explicitly initialized with + initApplicationClassLoader(ClassLoader) the method returns + null to indicate that Thread.getContextClassLoader() should be used. +

+

+
+
+
+
+ +

+initApplicationClassLoader

+
+public final void initApplicationClassLoader(java.lang.ClassLoader loader)
+
+
Set explicit class loader to use when searching for Java classes. +

+

+
See Also:
getApplicationClassLoader()
+
+
+
+ +

+doTopCall

+
+protected java.lang.Object doTopCall(Callable callable,
+                                     Context cx,
+                                     Scriptable scope,
+                                     Scriptable thisObj,
+                                     java.lang.Object[] args)
+
+
Execute top call to script or function. + When the runtime is about to execute a script or function that will + create the first stack frame with scriptable code, it calls this method + to perform the real call. In this way execution of any script + happens inside this function. +

+

+
+
+
+
+ +

+observeInstructionCount

+
+protected void observeInstructionCount(Context cx,
+                                       int instructionCount)
+
+
Implementation of + Context.observeInstructionCount(int instructionCount). + This can be used to customize Context without introducing + additional subclasses. +

+

+
+
+
+
+ +

+onContextCreated

+
+protected void onContextCreated(Context cx)
+
+
+
+
+
+
+ +

+onContextReleased

+
+protected void onContextReleased(Context cx)
+
+
+
+

+public final void removeListener(ContextFactory.Listener listener)
+
+
+
+
+
+
+ +

+isSealed

+
+public final boolean isSealed()
+
+
Checks if this is a sealed ContextFactory. +

+

+
See Also:
seal()
+
+
+
+ +

+seal

+
+public final void seal()
+
+
Seal this ContextFactory so any attempt to modify it like to add or + remove its listeners will throw an exception. +

+

+

+checkNotSealed

+
+protected final void checkNotSealed()
+
+
+
+
+
+
+ +

+call

+
+public final java.lang.Object call(ContextAction action)
+
+
Call ContextAction.run(Context cx) + using the Context instance associated with the current thread. + If no Context is associated with the thread, then + makeContext() will be called to construct + new Context instance. The instance will be temporary associated + with the thread during call to ContextAction.run(Context). +

+

+
See Also:
call(ContextAction), +Context.call(ContextFactory factory, Callable callable, + Scriptable scope, Scriptable thisObj, + Object[] args)
+
+
+
+ +

+enterContext

+
+public Context enterContext()
+
+
Get a context associated with the current thread, creating one if need + be. The Context stores the execution state of the JavaScript engine, so + it is required that the context be entered before execution may begin. + Once a thread has entered a Context, then getCurrentContext() may be + called to find the context that is associated with the current thread. +

+ Calling enterContext() will return either the Context + currently associated with the thread, or will create a new context and + associate it with the current thread. Each call to + enterContext() must have a matching call to + Context.exit(). +

+      Context cx = contextFactory.enterContext();
+      try {
+          ...
+          cx.evaluateString(...);
+      } finally {
+          Context.exit();
+      }
+ 
+ Instead of using enterContext(), exit() pair consider + using call(ContextAction) which guarantees proper association + of Context instances with the current thread. + With this method the above example becomes: +
+      ContextFactory.call(new ContextAction() {
+          public Object run(Context cx) {
+              ...
+              cx.evaluateString(...);
+              return null;
+          }
+      });
+ 
+

+

+ +
Returns:
a Context associated with the current thread

Context.getCurrentContext(), +Context.exit(), +call(ContextAction)
+

+enter

+
+public final Context enter()
+
+
Deprecated. use enterContext() instead +

+

+ +
Returns:
a Context associated with the current thread
+
+
+
+ +

+exit

+
+public final void exit()
+
+
Deprecated. Use Context.exit() instead. +

+

+
+
+
+
+ +

+enterContext

+
+public final Context enterContext(Context cx)
+
+
Get a Context associated with the current thread, using the given + Context if need be. +

+ The same as enterContext() except that cx + is associated with the current thread and returned if the current thread + has no associated context and cx is not associated with any + other thread. +

+

+
Parameters:
cx - a Context to associate with the thread if possible +
Returns:
a Context associated with the current thread +
Throws: +
java.lang.IllegalStateException - if cx is already associated + with a different thread

+ voidwarning(java.lang.String message, + java.lang.String sourceName, + int line, + java.lang.String lineSource, + int lineOffset) + +
+          Report a warning.
+  +

+ + + + + + + + +
+Method Detail
+ +

+warning

+
+void warning(java.lang.String message,
+             java.lang.String sourceName,
+             int line,
+             java.lang.String lineSource,
+             int lineOffset)
+
+
Report a warning. + + The implementing class may choose to ignore the warning + if it desires. +

+

+
Parameters:
message - a String describing the warning
sourceName - a String describing the JavaScript source + where the warning occured; typically a filename or URL
line - the line number associated with the warning
lineSource - the text of the line (may be null)
lineOffset - the offset into lineSource where problem was detected
+
+
+
+ +

+error

+
+void error(java.lang.String message,
+           java.lang.String sourceName,
+           int line,
+           java.lang.String lineSource,
+           int lineOffset)
+
+
Report an error. + + The implementing class is free to throw an exception if + it desires. + + If execution has not yet begun, the JavaScript engine is + free to find additional errors rather than terminating + the translation. It will not execute a script that had + errors, however. +

+

+
Parameters:
message - a String describing the error
sourceName - a String describing the JavaScript source + where the error occured; typically a filename or URL
line - the line number associated with the error
lineSource - the text of the line (may be null)
lineOffset - the offset into lineSource where problem was detected
+
+
+
+ +

+runtimeError

+
+EvaluatorException runtimeError(java.lang.String message,
+                                java.lang.String sourceName,
+                                int line,
+                                java.lang.String lineSource,
+                                int lineOffset)
+
+
Creates an EvaluatorException that may be thrown. + + runtimeErrors, unlike errors, will always terminate the + current script. +

+

+
Parameters:
message - a String describing the error
sourceName - a String describing the JavaScript source + where the error occured; typically a filename or URL
line - the line number associated with the error
lineSource - the text of the line (may be null)
lineOffset - the offset into lineSource where problem was detected +
Returns:
an EvaluatorException that will be thrown.

+FunctionObject

+
+public FunctionObject(java.lang.String name,
+                      java.lang.reflect.Member methodOrConstructor,
+                      Scriptable scope)
+
+
Create a JavaScript function object from a Java method. + +

The member argument must be either a java.lang.reflect.Method + or a java.lang.reflect.Constructor and must match one of two forms.

+ + The first form is a member with zero or more parameters + of the following types: Object, String, boolean, Scriptable, + int, or double. The Long type is not supported + because the double representation of a long (which is the + EMCA-mandated storage type for Numbers) may lose precision. + If the member is a Method, the return value must be void or one + of the types allowed for parameters.

+ + The runtime will perform appropriate conversions based + upon the type of the parameter. A parameter type of + Object specifies that no conversions are to be done. A parameter + of type String will use Context.toString to convert arguments. + Similarly, parameters of type double, boolean, and Scriptable + will cause Context.toNumber, Context.toBoolean, and + Context.toObject, respectively, to be called.

+ + If the method is not static, the Java 'this' value will + correspond to the JavaScript 'this' value. Any attempt + to call the function with a 'this' value that is not + of the right Java type will result in an error.

+ + The second form is the variable arguments (or "varargs") + form. If the FunctionObject will be used as a constructor, + the member must have the following parameters +

+      (Context cx, Object[] args, Function ctorObj,
+       boolean inNewExpr)
+ and if it is a Method, be static and return an Object result.

+ + Otherwise, if the FunctionObject will not be used to define a + constructor, the member must be a static Method with parameters + (Context cx, Scriptable thisObj, Object[] args, + Function funObj) +

+ and an Object result.

+ + When the function varargs form is called as part of a function call, + the args parameter contains the + arguments, with thisObj + set to the JavaScript 'this' value. funObj + is the function object for the invoked function.

+ + When the constructor varargs form is called or invoked while evaluating + a new expression, args contains the + arguments, ctorObj refers to this FunctionObject, and + inNewExpr is true if and only if a new + expression caused the call. This supports defining a function that + has different behavior when called as a constructor than when + invoked as a normal function call. (For example, the Boolean + constructor, when called as a function, + will convert to boolean rather than creating a new object.)

+

+

+
Parameters:
name - the name of the function
methodOrConstructor - a java.lang.reflect.Method or a java.lang.reflect.Constructor + that defines the object
scope - enclosing scope of function

Scriptable

public class ImporterTopLevel
extends org.mozilla.javascript.IdScriptableObject
+ + +

+Class ImporterTopLevel + + This class defines a ScriptableObject that can be instantiated + as a top-level ("global") object to provide functionality similar + to Java's "import" statement. +

+ This class can be used to create a top-level scope using the following code: +

+  Scriptable scope = new ImporterTopLevel(cx);
+ 
+ Then JavaScript code will have access to the following methods: +
    +
  • importClass - will "import" a class by making its unqualified name + available as a property of the top-level scope +
  • importPackage - will "import" all the classes of the package by + searching for unqualified names as classes qualified + by the given package. +
+ The following code from the shell illustrates this use: +
+ js> importClass(java.io.File)
+ js> f = new File('help.txt')
+ help.txt
+ js> importPackage(java.util)
+ js> v = new Vector()

public interface Scriptable
+ + +

+This is interface that all objects in JavaScript must implement. + The interface provides for the management of properties and for + performing conversions. +

+ Host system implementors may find it easier to extend the ScriptableObject + class rather than implementing Scriptable when writing host objects. +

+ There are many static methods defined in ScriptableObject that perform + the multiple calls to the Scriptable interface needed in order to + manipulate properties in prototype chains. +

+getClassName

+
+java.lang.String getClassName()
+
+
Get the name of the set of objects implemented by this Java class. + This corresponds to the [[Class]] operation in ECMA and is used + by Object.prototype.toString() in ECMA.

+ See ECMA 8.6.2 and 15.2.4.2. +

+
+java.lang.Object get(java.lang.String name,
+                     Scriptable start)
+
+
Get a named property from the object. + + Looks property up in this object and returns the associated value + if found. Returns NOT_FOUND if not found. + Note that this method is not expected to traverse the prototype + chain. This is different from the ECMA [[Get]] operation. + + Depending on the property selector, the runtime will call + this method or the form of get that takes an + integer: + + + + + + + + + + +
JavaScript codeJava code
a.b a.get("b", a)
a["foo"] a.get("foo", a)
a[3] a.get(3, a)
a["3"] a.get(3, a)
a[3.0] a.get(3, a)
a["3.0"] a.get("3.0", a)
a[1.1] a.get("1.1", a)
a[-4] a.get(-4, a)
+

+ The values that may be returned are limited to the following: +

    +
  • java.lang.Boolean objects
  • +
  • java.lang.String objects
  • +
  • java.lang.Number objects
  • +
  • org.mozilla.javascript.Scriptable objects
  • +
  • null
  • +
  • The value returned by Context.getUndefinedValue()
  • +
  • NOT_FOUND
  • +
+

+

+

+
+
+
+ +

+get

+
+java.lang.Object get(int index,
+                     Scriptable start)
+
+
Get a property from the object selected by an integral index. + + Identical to get(String, Scriptable) except that + an integral index is used to select the property. +

+

+
Parameters:
index - the numeric index for the property
start - the object in which the lookup began +
Returns:
the value of the property (may be null), or NOT_FOUND

get(String,Scriptable)
+
+
+
+ +

+has

+
+boolean has(java.lang.String name,
+            Scriptable start)
+
+
Indicates whether or not a named property is defined in an object. + + Does not traverse the prototype chain.

+ + The property is specified by a String name + as defined for the get method.

+

+

+
Parameters:
name - the name of the property
start - the object in which the lookup began +
Returns:
true if and only if the named property is found in the object
See Also:
get(String, Scriptable), +ScriptableObject.getProperty(Scriptable, String)
+
+
+
+ +

+has

+
+boolean has(int index,
+            Scriptable start)
+
+
Indicates whether or not an indexed property is defined in an object. + + Does not traverse the prototype chain.

+ + The property is specified by an integral index + as defined for the get method.

+

+

+
Parameters:
index - the numeric index for the property
start - the object in which the lookup began +
Returns:
true if and only if the indexed property is found in the object
See Also:
get(int, Scriptable), +ScriptableObject.getProperty(Scriptable, int)
+
+
+
+ +

+put

+
+void put(java.lang.String name,
+         Scriptable start,
+         java.lang.Object value)
+
+
Sets a named property in this object. +

+ The property is specified by a string name + as defined for get. +

+ The possible values that may be passed in are as defined for + get. A class that implements this method may choose + to ignore calls to set certain properties, in which case those + properties are effectively read-only.

+ For properties defined in a prototype chain, + use putProperty in ScriptableObject.

+ Note that if a property a is defined in the prototype p + of an object o, then evaluating o.a = 23 will cause + set to be called on the prototype p with + o as the start parameter. + To preserve JavaScript semantics, it is the Scriptable + object's responsibility to modify o.

+ This design allows properties to be defined in prototypes and implemented + in terms of getters and setters of Java values without consuming slots + in each instance.

+

+ The values that may be set are limited to the following: +

    +
  • java.lang.Boolean objects
  • +
  • java.lang.String objects
  • +
  • java.lang.Number objects
  • +
  • org.mozilla.javascript.Scriptable objects
  • +
  • null
  • +
  • The value returned by Context.getUndefinedValue()
  • +

+ Arbitrary Java objects may be wrapped in a Scriptable by first calling + Context.toObject. This allows the property of a JavaScript + object to contain an arbitrary Java object as a value.

+ Note that has will be called by the runtime first before + set is called to determine in which object the + property is defined. + Note that this method is not expected to traverse the prototype chain, + which is different from the ECMA [[Put]] operation. +

+

+
Parameters:
name - the name of the property
start - the object whose property is being set
value - value to set the property to

has(String, Scriptable), +get(String, Scriptable), +ScriptableObject.putProperty(Scriptable, String, Object), +Context.toObject(Object, Scriptable)

+put

+
+void put(int index,
+         Scriptable start,
+         java.lang.Object value)
+
+
Sets an indexed property in this object. +

+ The property is specified by an integral index + as defined for get.

+ + Identical to put(String, Scriptable, Object) except that + an integral index is used to select the property. +

+

+
Parameters:
index - the numeric index for the property
start - the object whose property is being set
value - value to set the property to
See Also:
has(int, Scriptable), +get(int, Scriptable), +ScriptableObject.putProperty(Scriptable, int, Object), +Context.toObject(Object, Scriptable)
+
+
+
+ +

+delete

+
+void delete(java.lang.String name)
+
+
Removes a property from this object. + This operation corresponds to the ECMA [[Delete]] except that + the no result is returned. The runtime will guarantee that this + method is called only if the property exists. After this method + is called, the runtime will call Scriptable.has to see if the + property has been removed in order to determine the boolean + result of the delete operator as defined by ECMA 11.4.1. +

+ A property can be made permanent by ignoring calls to remove + it.

+ The property is specified by a String name + as defined for get. +

+ To delete properties defined in a prototype chain, + see deleteProperty in ScriptableObject. +

+

+
Parameters:
name - the identifier for the property
See Also:
get(String, Scriptable), +ScriptableObject.deleteProperty(Scriptable, String)
+
+
+
+ +

+delete

+
+void delete(int index)
+
+
Removes a property from this object. + + The property is specified by an integral index + as defined for get. +

+ To delete properties defined in a prototype chain, + see deleteProperty in ScriptableObject. + + Identical to delete(String) except that + an integral index is used to select the property. +

+

+
Parameters:
index - the numeric index for the property
See Also:
get(int, Scriptable), +ScriptableObject.deleteProperty(Scriptable, int)
+
+
+
+ +

+

+ +
Returns:
the prototype
+
+
+
+ +

+setPrototype

+
+void setPrototype(Scriptable prototype)
+
+
Set the prototype of the object. +

+

+
Parameters:
prototype - the prototype to set
+
+
+
+ +

+getParentScope

+
+Scriptable getParentScope()
+
+
Get the parent scope of the object. +

+

+ +
Returns:
the parent scope
+
+
+
+ +

+setParentScope

+
+void setParentScope(Scriptable parent)
+
+
Set the parent scope of the object. +

+

+
Parameters:
parent - the parent scope to set
+
+
+
+ +

+getIds

+
+java.lang.Object[] getIds()
+
+
Get an array of property ids. + + Not all property ids need be returned. Those properties + whose ids are not returned are considered non-enumerable. +

+

+ +
Returns:
an array of Objects. Each entry in the array is either + a java.lang.String or a java.lang.Number
+
+
+
+ +

+getDefaultValue

+
+java.lang.Object getDefaultValue(java.lang.Class hint)
+
+
Get the default value of the object with a given hint. + The hints are String.class for type String, Number.class for type + Number, Scriptable.class for type Object, and Boolean.class for + type Boolean.

+ + A hint of null means "no hint". + + See ECMA 8.6.2.6. +

+

+
Parameters:
hint - the type hint +
Returns:
the default value
+
+
+
+ +

+hasInstance

+
+boolean hasInstance(Scriptable instance)
+
+
The instanceof operator. + +

+ The JavaScript code "lhs instanceof rhs" causes rhs.hasInstance(lhs) to + be called. + +

+ The return value is implementation dependent so that embedded host objects can + return an appropriate value. See the JS 1.3 language documentation for more + detail. + +

This operator corresponds to the proposed EMCA [[HasInstance]] operator. +

+

+
Parameters:
instance - The value that appeared on the LHS of the instanceof + operator +
Returns:
an implementation dependent value

+defineClass

+                        throws java.lang.IllegalAccessException,
+                               java.lang.InstantiationException,
+                               java.lang.reflect.InvocationTargetException
+
+
Defines JavaScript objects from a Java class that implements Scriptable. + + If the given class has a method +
+ static void init(Context cx, Scriptable scope, boolean sealed);
+ + or its compatibility form +
+ static void init(Scriptable scope);
+ + then it is invoked and no further initialization is done.

+ + However, if no such a method is found, then the class's constructors and + methods are used to initialize a class in the following manner.

+ + First, the zero-parameter constructor of the class is called to + create the prototype. If no such constructor exists, + a EvaluatorException is thrown.

+ + Next, all methods are scanned for special prefixes that indicate that they + have special meaning for defining JavaScript objects. + These special prefixes are +

    +
  • jsFunction_ for a JavaScript function +
  • jsStaticFunction_ for a JavaScript function that + is a property of the constructor +
  • jsGet_ for a getter of a JavaScript property +
  • jsSet_ for a setter of a JavaScript property +
  • jsConstructor for a JavaScript function that + is the constructor +

+ + If the method's name begins with "jsFunction_", a JavaScript function + is created with a name formed from the rest of the Java method name + following "jsFunction_". So a Java method named "jsFunction_foo" will + define a JavaScript method "foo". Calling this JavaScript function + will cause the Java method to be called. The parameters of the method + must be of number and types as defined by the FunctionObject class. + The JavaScript function is then added as a property + of the prototype.

+ + If the method's name begins with "jsStaticFunction_", it is handled + similarly except that the resulting JavaScript function is added as a + property of the constructor object. The Java method must be static. + + If the method's name begins with "jsGet_" or "jsSet_", the method is + considered to define a property. Accesses to the defined property + will result in calls to these getter and setter methods. If no + setter is defined, the property is defined as READONLY.

+ + If the method's name is "jsConstructor", the method is + considered to define the body of the constructor. Only one + method of this name may be defined. + If no method is found that can serve as constructor, a Java + constructor will be selected to serve as the JavaScript + constructor in the following manner. If the class has only one + Java constructor, that constructor is used to define + the JavaScript constructor. If the the class has two constructors, + one must be the zero-argument constructor (otherwise an + EvaluatorException would have already been thrown + when the prototype was to be created). In this case + the Java constructor with one or more parameters will be used + to define the JavaScript constructor. If the class has three + or more constructors, an EvaluatorException + will be thrown.

+ + Finally, if there is a method +

+ static void finishInit(Scriptable scope, FunctionObject constructor,
+                        Scriptable prototype)
+ + it will be called to finish any initialization. The scope + argument will be passed, along with the newly created constructor and + the newly created prototype.

+

+

+
+
+
+
Parameters:
scope - The scope in which to define the constructor.
clazz - The Java class to use to define the JavaScript objects + and properties. +
Throws: +
java.lang.IllegalAccessException - if access is not available + to a reflected class member +
java.lang.InstantiationException - if unable to instantiate + the named class +

+defineProperty

+
+public void defineProperty(java.lang.String propertyName,
+                           java.lang.Class clazz,
+                           int attributes)
+
+
Define a JavaScript property with getter and setter side effects. + + If the setter is not found, the attribute READONLY is added to + the given attributes.

+ + The getter must be a method with zero parameters, and the setter, if + found, must be a method with one parameter.

+

+

+
+
+
+
Parameters:
propertyName - the name of the property to define. This name + also affects the name of the setter and getter + to search for. If the propertyId is "foo", then + clazz will be searched for "getFoo" + and "setFoo" methods.
clazz - the Java class to search for the getter and setter
attributes - the attributes of the JavaScript property

+                           java.lang.reflect.Method getter,
+                           java.lang.reflect.Method setter,
+                           int attributes)
+
+
Define a JavaScript property. + + Use this method only if you wish to define getters and setters for + a given property in a ScriptableObject. To create a property without + special getter or setter side effects, use + defineProperty(String,int). + + If setter is null, the attribute READONLY is added to + the given attributes.

+ + Several forms of getters or setters are allowed. In all cases the + type of the value parameter can be any one of the following types: + Object, String, boolean, Scriptable, byte, short, int, long, float, + or double. The runtime will perform appropriate conversions based + upon the type of the parameter (see description in FunctionObject). + The first forms are nonstatic methods of the class referred to + by 'this': +

+ Object getFoo();
+ void setFoo(SomeType value);
+ Next are static methods that may be of any class; the object whose + property is being accessed is passed in as an extra argument: +
+ static Object getFoo(Scriptable obj);
+ static void setFoo(Scriptable obj, SomeType value);
+ Finally, it is possible to delegate to another object entirely using + the delegateTo parameter. In this case the methods are + nonstatic methods of the class delegated to, and the object whose + property is being accessed is passed in as an extra argument: +
+ Object getFoo(Scriptable obj);
+ void setFoo(Scriptable obj, SomeType value);
+

+

+
+
+
+
Parameters:
propertyName - the name of the property to define.
delegateTo - an object to call the getter and setter methods on, + or null, depending on the form used above.
getter - the method to invoke to get the value of the property
setter - the method to invoke to set the value of the property
attributes - the attributes of the JavaScript property

+
+
Search for names in a class, adding the resulting methods + as properties. + +

+
+java.lang.Object
+  extended by org.mozilla.javascript.SecurityController
+
+
+
+
public abstract class SecurityController
extends java.lang.Object
+ + +

+This class describes the support needed to implement security. +

+ Three main pieces of functionality are required to implement + security for JavaScript. First, it must be possible to define + classes with an associated security domain. (This security + domain may be any object incorporating notion of access + restrictions that has meaning to an embedding; for a client-side + JavaScript embedding this would typically be + java.security.ProtectionDomain or similar object depending on an + origin URL and/or a digital certificate.) + Next it must be possible to get a security domain object that + allows a particular action only if all security domains + associated with code on the current Java stack allows it. And + finally, it must be possible to execute script code with + associated security domain injected into Java stack. +

+ These three pieces of functionality are encapsulated in the + SecurityController class. +

public class Synchronizer
extends org.mozilla.javascript.Delegator
+ + +

+This class provides support for implementing Java-style synchronized + methods in Javascript. + + Synchronized functions are created from ordinary Javascript + functions by the Synchronizer constructor, e.g. + new Packages.org.mozilla.javascript.Synchronizer(fun). + The resulting object is a function that establishes an exclusive + lock on the this object of its invocation. + + The Rhino shell provides a short-cut for the creation of + synchronized methods: sync(fun) has the same effect as + calling the above constructor. +

+Class ScriptableOutputStream is an ObjectOutputStream used + to serialize JavaScript objects and functions. Note that + compiled functions currently cannot be serialized, only + interpreted functions. The top-level scope containing the + object is not written out, but is instead replaced with + another top-level object when the ScriptableInputStream + reads in this object. Also, object corresponding to names + added to the exclude list are not written out but instead + are looked up during deserialization. This approach avoids + the creation of duplicate copies of standard objects + during deserialization. +

The member argument must be either a java.lang.reflect.Method + * or a java.lang.reflect.Constructor and must match one of two forms.

+ * + * The first form is a member with zero or more parameters + * of the following types: Object, String, boolean, Scriptable, + * int, or double. The Long type is not supported + * because the double representation of a long (which is the + * EMCA-mandated storage type for Numbers) may lose precision. + * If the member is a Method, the return value must be void or one + * of the types allowed for parameters.

+ * + * The runtime will perform appropriate conversions based + * upon the type of the parameter. A parameter type of + * Object specifies that no conversions are to be done. A parameter + * of type String will use Context.toString to convert arguments. + * Similarly, parameters of type double, boolean, and Scriptable + * will cause Context.toNumber, Context.toBoolean, and + * Context.toObject, respectively, to be called.

+ * + * If the method is not static, the Java 'this' value will + * correspond to the JavaScript 'this' value. Any attempt + * to call the function with a 'this' value that is not + * of the right Java type will result in an error.

+ * + * The second form is the variable arguments (or "varargs") + * form. If the FunctionObject will be used as a constructor, + * the member must have the following parameters + *

+     *      (Context cx, Object[] args, Function ctorObj,
+     *       boolean inNewExpr)
+ * and if it is a Method, be static and return an Object result.

+ * + * Otherwise, if the FunctionObject will not be used to define a + * constructor, the member must be a static Method with parameters + * (Context cx, Scriptable thisObj, Object[] args, + * Function funObj) + *

+     * and an Object result.

+ * + * When the function varargs form is called as part of a function call, + * the args parameter contains the + * arguments, with thisObj + * set to the JavaScript 'this' value. funObj + * is the function object for the invoked function.

+ * + * When the constructor varargs form is called or invoked while evaluating + * a new expression, args contains the + * arguments, ctorObj refers to this FunctionObject, and + * inNewExpr is true if and only if a new + * expression caused the call. This supports defining a function that + * has different behavior when called as a constructor than when + * invoked as a normal function call. (For example, the Boolean + * constructor, when called as a function, + * will convert to boolean rather than creating a new object.)
