Many times, while using RemoteObject, instead of processing the result of a remote method invocation in every result handler, you may want a mechanism to process the result before all the result handlers are notified.
convertResultHandler is such a property which was introduced in RemoteObject to process the result before sending it across to all the result handlers.
A sample implementation can be as simple as converting the result to ArrayCollection if its an Array –
public function convertResultHandler(result:*, operation:AbstractOperation):*
// convert result to ArrayCollection
if (result is Array)
return new ArrayCollection(result as Array);
A similar property exists for WebService also.
