T - type of result for AsyncCallback.onSuccess(Object) if the
operation completed successfully.public abstract class Handler<T> extends Object implements Callable<T>
Typically an RPC service implementation will extend this class and use Guice injection to manage its state. For example:
class Foo extends Handler<Result> {
interface Factory {
Foo create(... args ...);
}
@Inject
Foo(state, @Assisted args) { ... }
Result get() throws Exception { ... }
}
