Constructor Details

NativeIterator

private NativeIterator()

Only for constructing the prototype object.

NativeIterator

private NativeIterator(Object objectIterator)

Method Details

init

static void init(Context cx,
 ScriptableObject scope,
 boolean sealed)

getStopIterationObject

public static 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 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 interface Scriptable

Specified by:

getClassName in class ScriptableObject

initPrototypeId

protected void initPrototypeId(int id)

Overrides:

initPrototypeId in class IdScriptableObject

execIdCall

public Object execIdCall(IdFunctionObject f,
 Context cx,
 Scriptable scope,
 Scriptable thisObj,
 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 interface IdFunctionCall

Overrides:

execIdCall in class IdScriptableObject

jsConstructor

private static Object jsConstructor(Context cx,
 Scriptable scope,
 Scriptable thisObj,
 Object[] args)

next

private Object next(Context cx,
 Scriptable scope)

getJavaIterator

private static Iterator<?> getJavaIterator(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(String s)

Overrides:

findPrototypeId in class IdScriptableObject
