public abstract class AbstractGridRendererConnector<T>
extends AbstractRendererConnector<T>

An abstract base class for renderer connectors. A renderer connector is used to link a client-side Renderer to a server-side Renderer. As a connector, it can use the regular Vaadin RPC and shared state mechanism to pass additional state and information between the client and the server. This base class itself only uses the basic SharedState and no RPC interfaces.
