Method Details

broadcast

public void broadcast(ConnectedMessage connection,
 IWebSocketPushMessage message)

Processes the given message in the page and session identified by the given Web Socket connection. The message is sent as an event to the Page and components of the session allowing the components to be updated. This method can be invoked from any thread, even a non-wicket thread. By default all processing is done in the caller thread. Use WebSocketSettings.setWebSocketPushMessageExecutor(org.apache.wicket.protocol.ws.concurrent.Executor) to move processing to background threads. If the given connection is no longer open then the broadcast is silently ignored.

Parameters:

connection - The Web Socket connection that identifies the page and session

message - The push message event

broadcastAll

public void broadcastAll(Application application,
 IWebSocketPushMessage message)

Processes the given message in all pages that have active Web Socket connections. The message is sent as an event to the Page and components of the session allowing the components to be updated. This method can be invoked from any thread, even a non-wicket thread. By default all processing is done in the caller thread. Use WebSocketSettings.setWebSocketPushMessageExecutor(org.apache.wicket.protocol.ws.concurrent.Executor) to move processing to background threads. If some connections are not in valid state they are silently ignored.

Parameters:

application - The wicket application

message - The push message event

broadcastAllInSession

public void broadcastAllInSession(Application application,
 String sessionId,
 IWebSocketPushMessage message)

Processes the given message in all pages in a given session that have active Web Socket connections. The message is sent as an event to the Page and components of the session allowing the components to be updated. This method can be invoked from any thread, even a non-wicket thread. By default all processing is done in the caller thread. Use WebSocketSettings.setWebSocketPushMessageExecutor(org.apache.wicket.protocol.ws.concurrent.Executor) to move processing to background threads. If some connections are not in valid state they are silently ignored.

Parameters:

application - The wicket application

sessionId - The session ID

message - The push message event

broadcastAllMatchingFilter

public void broadcastAllMatchingFilter(Application application,
 IWebSocketConnectionRegistry.IConnectionsFilter connectionsFilter,
 IWebSocketPushMessage message)

Processes the given message in all pages in a given session that have active Web Socket connections and match the given filter. The message is sent as an event to the Page and components of the session allowing the components to be updated. This method can be invoked from any thread, even a non-wicket thread. By default all processing is done in the caller thread. Use WebSocketSettings.setWebSocketPushMessageExecutor(org.apache.wicket.protocol.ws.concurrent.Executor) to move processing to background threads. If some connections are not in valid state they are silently ignored.

Parameters:

application - The wicket application

connectionsFilter - the IWebSocketConnectionRegistry.IConnectionsFilter

message - The push message event
