Method Detail

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

getMaxInstanceId

protected int getMaxInstanceId()

Description copied from class: IdScriptableObject

Get maximum id findInstanceIdInfo can generate.

Overrides:

getMaxInstanceId in class IdScriptableObject

                                       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

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:

fillConstructorProperties

protected void fillConstructorProperties(IdFunctionObject ctor)

Overrides:

fillConstructorProperties in class IdScriptableObject

initPrototypeId

protected void initPrototypeId(int id)

Overrides:

initPrototypeId in class IdScriptableObject

Specified by:

execIdCall in interface IdFunctionCall

Overrides:

execIdCall in class IdScriptableObject

has

public boolean has(int index,
                   Scriptable start)

Description copied from class: ScriptableObject

                java.lang.Object value)

Description copied from class: ScriptableObject

Sets the value of the named property, creating it if need be.

If the property was created using defineProperty, the appropriate setter method is called.

If the property's attributes include READONLY, no action is taken. This method will actually set the property in the start object.

Specified by:

put in interface Scriptable

Overrides:

put in class IdScriptableObject
