@Deprecated
public abstract class AbstractDispatchImpl
extends Object
implements Dispatch

This is the server-side implementation of the Dispatch service with an arbitrary action type, for which the client-side async service is DispatchAsync.

This class is closely related to DispatchServiceImpl. In fact, this class wouldn't be needed, but we use it to workaround a GWT limitation described in DispatchAsync.
