Method Details

init

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

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

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

js_set

private Object js_set(Object k,
 Object v)

js_delete

private Object js_delete(Object arg)

js_get

private Object js_get(Object arg)

js_has

private Object js_has(Object arg)

js_getSize

private Object js_getSize()

js_iterator

private Object js_iterator(Scriptable scope,
 NativeCollectionIterator.Type type)

js_clear

private Object js_clear()

js_forEach

private Object js_forEach(Context cx,
 Scriptable scope,
 Object arg1,
 Object arg2)

loadFromIterable

static void loadFromIterable(Context cx,
 Scriptable scope,
 ScriptableObject map,
 Object arg1)

If an "iterable" object was passed to the constructor, there are many many things to do... Make this static because NativeWeakMap has the exact same requirement.

realThis

private static NativeMap realThis(Scriptable thisObj,
 IdFunctionObject f)

initPrototypeId

protected void initPrototypeId(int id)

Overrides:

initPrototypeId in class IdScriptableObject

findPrototypeId

protected int findPrototypeId(Symbol k)

Overrides:

findPrototypeId in class IdScriptableObject

findPrototypeId

protected int findPrototypeId(String s)

Overrides:

findPrototypeId in class IdScriptableObject

key

static Object key(Object[] args)

Extracts the key from the first args entry if any and takes care of the Delegator. This is used by NativeSet, NativeWeakMap, and NativeWekSet also.

Parameters:

args - the args

Returns:

the first argument (de-delegated) or undefined if there is no element in args
