Detailed Description

template<class T>
class disti::AttributeChangedEventEmitter< T >

helper for class for emitting attribute changed events in generated code this class does two things:
1) It calls NotifyAttributeChanged if the attribute changed 2) It emits an event if EmitEvent() was set to true and if the Container type is DisplayObject. It can't emit events for top level display frames since they don't have a handle() method.
