+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
