| Class | public class ItemResponder |
| Implements | IResponder |
mx.rpc.IResponder interface.
It represents a responder that lets you specify methods to be
called when a request is completed, either successfully or with an error.
The class object can also lets you provide data (a token) to be used by
the responder methods.
You use an ItemResponder object in the catch statement
of a try block that might result in getting remote data, as shown in the following
code:
import mx.collections.ItemResponder;
//...
try
{
//...
cursor.moveNext();
}
catch(e:ItemPendingError)
{
e.addResponder(new ItemResponder(myResultFunction, myFaultFunction, {info:"..."}));
}
The result method specified must have the following signature:
public function myResultFunction(result:Object, token:Object = null):void;
The fault method specified must have the following signature:
public function myFaultFunction(error:Object, token:Object = null):void;
Any other signature will result in a runtime error.
