It is also possible to chain commands:
public class MyChainedCommand extends Command
{
[Inject]
public var event:MyCustomEvent;
[Inject]
public var model:MyModel;
override public function execute():void
{
model.updateData( event.myCustomEventPayload )
//the UPDATED_WITH_NEW_STUFF event triggers a command and is also received by
//a mediator to update a View Component, but only if a response is requested
if(event.responseNeeded)
dispatch( new MyCustomEvent( MyCustomEvent.UPDATED_WITH_NEW_STUFF, model.getCalculatedResponse() ) )
}
}
Using this approach it is possible to chain as many Commands as needed together. In the example above a conditional statement is used. If the condition is not met, the Command is not chained. This provides extreme flexibility within your Commands to perform work on your application.
