Constructor
CasaShape

Creates a new CasaShape
.
Instance properties
destroyed
destroyed:Boolean(read)
Determines if the object has been destroyed , or is still available for use . →
stage
override stage:Stage(read)
The Stage of the display object or if the display object is not added to the display list and StageReference is defined stage
will return the default stage; otherwise null
.
Overrides
- Shape.stage
Instance methods
destroy
function destroy() : void
Removes any event listeners and stops all internal processes to help allow for prompt garbage collection.
Always call
Calling destroy()
before deleting last object pointer. →destroy()
on a CASA display object also removes it from its current parent. getTotalEventListeners
function getTotalEventListeners(type:String = null) : uint
Reports the number of listeners for a specific event or the total listeners for all events. →
removeEventsForListener
function removeEventsForListener(listener:Function) : void
Removes all events that report to the specified listener. →
