Classpublic class ConcurrentTaskGroup
InheritanceConcurrentTaskGroup Inheritance TaskGroup Inheritance Task Inheritance flash.events.EventDispatcher

A TaskGroup implementation that executes its child Tasks concurrently. If a TaskGroup is started all the Tasks that were added to it will be started immediately. If a Taks gets added to a running TaskGroup, that Task will be started immediately. When all child Tasks have completed their operation this TaskGroup will fire its COMPLETE event. If a TaskGroup gets cancelled or suspended all child tasks that are still running will also be cancelled or suspended in turn. If a child Task throws an ERROR event and the ignoreChildErrors property of this TaskGroup is set to false, then all child tasks that are still running will be cancelled and the TaskGroup will fire an ERROR event.
