RequestListener (Rhino 3.2 Resource Adaptor API)

```
public interface RequestListener
```
Listener interface implemented by resource adaptors to receive request messages sent by other nodes. Requests differ from messages in that a response is expected.

Implementations of this interface are registered with the Message Facility using MessageFacility.setRequestListener(RequestListener).

For new work, it is recommended to use RequestListenerV2 instead of this interface.
