WebSocketApplication

public WebSocketApplication()

Method Detail

getWebSockets

protected java.util.Set<WebSocket> getWebSockets()

Returns a set of WebSockets, registered with the application. The returned set is unmodifiable, the possible modifications may cause exceptions.

Returns:

a set of WebSockets, registered with the application.

add

protected boolean add(WebSocket socket)

remove

public boolean remove(WebSocket socket)

createSocket

public WebSocket createSocket(ProtocolHandler handler,
                              WebSocketListener... listeners)

handshake

protected void handshake(HandShake handshake)
                  throws HandshakeException

Method is called, when initial WebSocket handshake process was completed, but WebSocketApplication may perform additional validation such as subprotocol or extension negotiation.

Throws:

HandshakeException - error occurred during the handshake.

onClose

public void onClose(WebSocket socket,
                    DataFrame frame)

Specified by:

onClose in interface WebSocketListener

Overrides:

onClose in class WebSocketAdapter

onConnect

public void onConnect(WebSocket socket)

Specified by:

onConnect in interface WebSocketListener

Overrides:

onConnect in class WebSocketAdapter

upgrade

public final boolean upgrade(HttpRequestPacket request)

Checks protocol specific information and queries #isApplicationRequest(Request) to see if the Request should be upgraded.

Returns:

true if the request should be upgraded to a WebSocket connection

isApplicationRequest

public abstract boolean isApplicationRequest(HttpRequestPacket request)

Checks application specific criteria to determine if this application can process the Request as a WebSocket connection.

Parameters:

request -

Returns:

true if this application can service this Request

getSupportedExtensions

public java.util.List<java.lang.String> getSupportedExtensions()

getSupportedProtocols

public java.util.List<java.lang.String> getSupportedProtocols(java.util.List<java.lang.String> subProtocol)
