All Implemented Interfaces:

Serializable

Direct Known Subclasses:

AbstractComponentState, JavaScriptExtensionState, JavaScriptManagerState, MultiSelectionModelState, SingleSelectionModelState

public class SharedState
extends Object
implements Serializable

Interface to be implemented by all shared state classes used to communicate basic information about a Connector from server to client. Shared state classes have to be declared in shared package to be accessible both for server and client code. 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 AbstractConnector.getState() to return the correct state type. This automatically causes a correct state object to be created. Subclasses of a Connector using shared state should also provide a subclass of the shared state class of the parent class to extend the state. A single Connector can only have one shared state object.
