Property Detail
interruptibleproperty
interruptible:Boolean  [read-only] [override]

The current Task can be interrupted. Invoking interrupt() for a Task that is not marked as interruptible may result in an error.


Implementation
    public function get interruptible():Boolean
Constructor Detail
InterruptibleTask()Constructor
public function InterruptibleTask(taskIdentifier:String = null)

Constructor.

Parameters
taskIdentifier:String (default = null)
Method Detail
customInterrupt()method
protected function customInterrupt():void

Sub-classes should override this method to implement interruption behavior (removing event listeners, pausing objects, etc.).

interrupt()method 
override public function interrupt():Boolean

Interrupt the current Task. Interruptions should be handled in such a way as to allow a subsequent call to run() to resume gracefully. This mehtod should trigger an event of type TaskEvent.INTERRUPTED.

Returns
Boolean — TRUE if the Task has been successfully interrupted
