Constructor.

Duplicates an instance of an Event subclass.

Returns a new Event object that is a copy of the original instance of the Event object. You do not normally call clone(); the EventDispatcher class calls it automatically when you redispatch an event—that is, when you call dispatchEvent(event) from a handler that is handling event.

The new Event object includes all the properties of the original.

When creating your own custom Event class, you must override the inherited Event.clone() method in order for it to duplicate the properties of your custom class. If you do not set all the properties that you add in your event subclass, those properties will not have the correct values when listeners handle the redispatched event.

In this example, PingEvent is a subclass of Event and therefore implements its own version of clone().

     class PingEvent extends Event {
         var URL:String;
         
     public override function clone():Event {
              return new PingEvent(type, bubbles, cancelable, URL);
        }
     }
     

The ExpressionBuilderEvent.CANCEL_EXPRESSION constant defines the value of the type property of the event object for an event that is dispatched when the agent clicks the Cancel button of a Expression Controlbar in Expression Builder UI.

The ExpressionBuilderEvent.EXPRESSION_CREATION_COMPLETED constant defines the value of the type property of the event object for an event that is dispatched when the agent clicks the Complete(OK) button of a Expression Controlbar in Expression Builder UI.

The ExpressionBuilderEvent.SAVE_EXPRESSION constant defines the value of the type property of the event object for an event that is dispatched when the agent clicks the Save button of a Expression Toolbar in Expression Builder UI.

The ExpressionBuilderEvent.UPDATE_EXPRESSION constant defines the value of the type property of the event object for an event that is dispatched when the agent clicks the Update button of a Expression Toolbar in Expression Builder UI.

The ExpressionBuilderEvent.VALLIDATE_EXPRESSION constant defines the value of the type property of the event object for an event that is dispatched when the agent clicks the Valiate button of a Expression Toolbar in Expression Builder UI.
