Examples of com.vaadin.shared.Connector

com.vaadin.shared.Connector
Interface implemented by all classes that are capable of communicating with the server or the client side.
A connector consists of a shared state (server sets the state and automatically communicates changes to the client) and the possibility to do RPC calls either from the server to the client or from the client to the server.

No classes should implement this interface directly, client side classes wanting to communicate with server side should implement {@link com.vaadin.client.ServerConnector} and server side classes shouldimplement {@link com.vaadin.server.ClientConnector}.
