Flex Remoting (RPC)

Flex Remoting... The Flex Remoting API is in the mx.rpc package and sub-packages.

Types of RPC services:

• HTTP - make HTTP calls to web servers
• Web Services - call SOAP + WSDL based web-services
• Remoting - call remote object servers such as ColdFusion or Java using BlazeDS

AsyncToken and Responder

Two objects are especially important when programming with Flex's Remoting/RPC APIs:

• AsyncToken
• Responder

1. An asynchronous call returns a token
   1. Any arbitrary information may be attached to the token for use later
2. A responder is attached to the token
3. ... (time passes)
4. The call will result in either a result or a fault
   1. The responder's result function is called
   2. Or the responder's fault function is called

   var token:AsyncToken = httpService.send();
   token.data = "some data";
   
   var responder:IResponder = new ExampleResponder();
   token.addResponder( responder );
   ...
