Method Detail

init

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

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 interface Scriptable

Specified by:

getClassName in class ScriptableObject

getTypeOf

public java.lang.String getTypeOf()

Gets the value to be returned by the typeof operator called on this object.

Overrides:

getTypeOf in class ScriptableObject

Returns:

"object"

See Also:

ScriptableObject.getTypeOf()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getMaxInstanceId

protected int getMaxInstanceId()

Description copied from class: IdScriptableObject

Get maximum id findInstanceIdInfo can generate.

Overrides:

getMaxInstanceId in class IdScriptableObject

findInstanceIdInfo

protected int findInstanceIdInfo(java.lang.String s)

Description copied from class: IdScriptableObject

Map name to id of instance property. Should return 0 if not found or the result of IdScriptableObject.instanceIdInfo(int, int).

Overrides:

findInstanceIdInfo in class IdScriptableObject

getInstanceIdName

protected java.lang.String getInstanceIdName(int id)

Description copied from class: IdScriptableObject

Map id back to property name it defines.

Overrides:

getInstanceIdName in class IdScriptableObject

getInstanceIdValue

protected java.lang.Object getInstanceIdValue(int id)

Description copied from class: IdScriptableObject

Get id value. * If id value is constant, descendant can call cacheIdValue to store * value in the permanent cache. * Default implementation creates IdFunctionObject instance for given id * and cache its value

Overrides:

getInstanceIdValue in class IdScriptableObject

setInstanceIdValue

protected void setInstanceIdValue(int id,
                                  java.lang.Object value)

Description copied from class: IdScriptableObject

Set or delete id value. If value == NOT_FOUND , the implementation should make sure that the following getInstanceIdValue return NOT_FOUND.

Overrides:

setInstanceIdValue in class IdScriptableObject

setInstanceIdAttributes

protected void setInstanceIdAttributes(int id,
                                       int attr)

Description copied from class: IdScriptableObject

Update the attributes of the given instance property. Classes which want to support changing property attributes via Object.defineProperty must override this method. The default implementation throws InternalError.

Overrides:

setInstanceIdAttributes in class IdScriptableObject

Parameters:

id - the instance property id

attr - the new attribute bitset

initPrototypeId

protected void initPrototypeId(int id)

Overrides:

initPrototypeId in class IdScriptableObject

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 interface IdFunctionCall

Overrides:

execIdCall in class IdScriptableObject

findPrototypeId

protected int findPrototypeId(Symbol k)

Overrides:

findPrototypeId in class IdScriptableObject

findPrototypeId

protected int findPrototypeId(java.lang.String s)

Overrides:

findPrototypeId in class IdScriptableObject
