public class WebSocketServerComponents
extends WebSocketComponents

A collection of components which are the resources needed for websockets such as ByteBufferPool, WebSocketExtensionRegistry, and DecoratedObjectFactory.

These components should be accessed through getWebSocketComponents(org.eclipse.jetty.server.handler.ContextHandler) so that the instance can be shared by being stored as a bean on the ContextHandler.

Method Details

ensureWebSocketComponents

public static WebSocketComponents ensureWebSocketComponents(Server server,
 ContextHandler contextHandler)

This ensures a WebSocketComponents is available at the ContextHandler attribute WEBSOCKET_COMPONENTS_ATTRIBUTE.

This should be called when the server is starting.

Servlet context attributes can be set with WEBSOCKET_BUFFER_POOL_ATTRIBUTE, WEBSOCKET_INFLATER_POOL_ATTRIBUTE and WEBSOCKET_DEFLATER_POOL_ATTRIBUTE to override the ByteBufferPool, DeflaterPool or InflaterPool used by the components, otherwise this will try to use the pools shared on the Server.

Parameters:

server - the server.

contextHandler - the ContextHandler.

Returns:

the WebSocketComponents that was created or found on the ServletContext.

ensureWebSocketComponents

public static WebSocketComponents ensureWebSocketComponents(Server server)

This ensures a WebSocketComponents is available on the Server attribute WEBSOCKET_COMPONENTS_ATTRIBUTE.

This should be called when the server is starting.

Server attributes can be set with WEBSOCKET_BUFFER_POOL_ATTRIBUTE, WEBSOCKET_INFLATER_POOL_ATTRIBUTE and WEBSOCKET_DEFLATER_POOL_ATTRIBUTE to override the ByteBufferPool, DeflaterPool or InflaterPool used by the components, otherwise this will try to use the pools shared on the Server.

Parameters:

server - the server.

Returns:

the WebSocketComponents that was created or found.
