Interface DispatchService

All Superinterfaces:

RemoteService

All Known Implementing Classes:

AbstractDispatchServiceImpl, DispatchServiceImpl, DispatchServiceImpl

Deprecated.

Please use DispatchService.

@Deprecated
public interface DispatchService
extends RemoteService

The base class of the synchronous dispatcher service. The server-side implementation is DispatchServiceImpl and the async client-side version is DispatchServiceAsync.

This class is closely related to Dispatch, in theory the latter wouldn't be needed, but we use it to workaround a GWT limitation described in com.gwtplatform.dispatch.client.DispatchAsync.
