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()

call

public java.lang.Object call(Context cx,
                             Scriptable scope,
                             Scriptable thisObj,
                             java.lang.Object[] args)

Description copied from interface: Function

Call the function. Note that the array of arguments is not guaranteed to have length greater than 0.

Specified by:

call in interface Callable

Specified by:

call in interface Function

Parameters:

cx - the current Context for this thread

scope - the scope to execute the function relative to. This is set to the value returned by getParentScope() except when the function is called from a closure.

thisObj - the JavaScript this object

args - the array of arguments

Returns:

the result of the call

construct

public Scriptable construct(Context cx,
                            Scriptable scope,
                            java.lang.Object[] args)

Description copied from interface: Function

Call the function as a constructor. This method is invoked by the runtime in order to satisfy a use of the JavaScript new operator. This method is expected to create a new object and return it.

Specified by:

construct in interface Function

Parameters:

cx - the current Context for this thread

scope - an enclosing scope of the caller except when the function is called from a closure.

args - the array of arguments

Returns:

the allocated object

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

                                   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:
