- * Interface to be implemented by all shared state classes used to communicate
- * basic information about a {@link Connector} from server to client.
- *
- * Shared state classes have to be declared in client side packages to be
- * accessible both for server and client code. They can be static nested classes
- * of a {@link ServerConnector}.
- *
- * Shared state objects are only sent from the server to the client, and any
- * modifications from the client should be performed via an RPC call that
- * modifies the authoritative state on the server.
- *
- * A shared state class should be a bean with getters and setters for each
- * field. Supported data types are simple Java types, other beans and maps and
- * arrays of these.
- *
- * On the client side the connector should override
- * {@link AbstractComponentConnector#createState()} to create the correct state
- * class and {@link AbstractComponentConnector#getState()} override the return
- * type.
- *
- * Subclasses of a {@link Connector} using shared state should also provide a
- * subclass of the shared state class of the parent class to extend the state. A
- * single {@link Connector} can only have one shared state object.
