Method Detail
-
init
static void init(Context cx, ScriptableObject scope, boolean sealed)
-
getStopIterationObject
public static java.lang.Object getStopIterationObject(Scriptable scope)
Get the value of the "StopIteration" object. Note that this value is stored in the top-level scope using "associateValue" so the value can still be found even if a script overwrites or deletes the global "StopIteration" property.- Parameters:
scope
- a scope whose parent chain reaches a top-level scope- Returns:
- the StopIteration object
-
getClassName
public java.lang.String getClassName()
Description copied from class:ScriptableObject
Return the name of the class.This is typically the same name as the constructor. Classes extending ScriptableObject must implement this abstract method.
- Specified by:
getClassName
in interfaceScriptable
- Specified by:
getClassName
in classScriptableObject
-
initPrototypeId
protected void initPrototypeId(int id)
- Overrides:
initPrototypeId
in classIdScriptableObject
-
execIdCall
public java.lang.Object execIdCall(IdFunctionObject f, Context cx, Scriptable scope, Scriptable thisObj, java.lang.Object[] args)
Description copied from class:IdScriptableObject
'thisObj' will be null if invoked as constructor, in which case * instance of Scriptable should be returned.- Specified by:
execIdCall
in interfaceIdFunctionCall
- Overrides:
execIdCall
in classIdScriptableObject
-
jsConstructor
private static java.lang.Object jsConstructor(Context cx, Scriptable scope, Scriptable thisObj, java.lang.Object[] args)
-
next
private java.lang.Object next(Context cx, Scriptable scope)
-
getJavaIterator
private static java.util.Iterator<?> getJavaIterator(java.lang.Object obj)
If "obj" is a java.util.Iterator or a java.lang.Iterable, return a wrapping as a JavaScript Iterator. Otherwise, return null. This method is in VMBridge since Iterable is a JDK 1.5 addition.

findPrototypeId
protected int findPrototypeId(java.lang.String s)
- Overrides:
