Package org.atmosphere.websocket

Class DefaultWebSocketProcessor

java.lang.Object

org.atmosphere.websocket.DefaultWebSocketProcessor

All Implemented Interfaces:

Serializable, WebSocketPingPongListener, WebSocketProcessor

public class DefaultWebSocketProcessor
extends Object
implements WebSocketProcessor, Serializable, WebSocketPingPongListener

Like the AsynchronousProcessor class, this class is responsible for dispatching WebSocket request to the proper WebSocket implementation. This class can be extended in order to support any protocol running on top websocket.

DefaultWebSocketProcessor

public DefaultWebSocketProcessor()

Method Details

configure

public WebSocketProcessor configure(AtmosphereConfig config)

Description copied from interface: WebSocketProcessor

Configure, or post construct a WebSocketProcessor

Specified by:

configure in interface WebSocketProcessor

Parameters:

config - an AtmosphereConfig

Returns:

this

handshake

public boolean handshake(javax.servlet.http.HttpServletRequest request)

Description copied from interface: WebSocketProcessor

Determine if the WebSocket's handshake data can be processed, or if the request be cancelled. Since it's container related native API, the HttpServletRequest might be null, so implementation must check for null.

Specified by:

handshake in interface WebSocketProcessor

Parameters:

request - HttpServletRequest

Returns:

true if the processing can continue, false if not.

registerWebSocketHandler

public WebSocketProcessor registerWebSocketHandler(String path,
 WebSocketProcessor.WebSocketHandlerProxy webSockethandler)

Description copied from interface: WebSocketProcessor

Register a WebSocketHandler

Specified by:

registerWebSocketHandler in interface WebSocketProcessor

Parameters:

path - the URI mapping the WebSocketHandler

webSockethandler - an instance of WebSocketProcessor.WebSocketHandlerProxy

Returns:

this

open

public final void open(WebSocket webSocket,
 AtmosphereRequest request,
 AtmosphereResponse response)
