Method Details

createWebSocket

Object createWebSocket(ServerUpgradeRequest upgradeRequest,
 ServerUpgradeResponse upgradeResponse,
 Callback callback)
                throws Exception

Creates a WebSocket endpoint instance from the incoming request.

If the implementation does not want to create a WebSocket endpoint instance, it is responsible to send a response (and completing the callback) and then it may return null.

If the implementation returns a non-null WebSocket endpoint instance, it must not write response content, nor completing the callback, but it may modify the response headers.

Parameters:

upgradeRequest - the upgrade request

upgradeResponse - the upgrade response

callback - the callback to complete only when returning null

Returns:

a WebSocket endpoint instance, or null if no WebSocket endpoint instance should be created for the given upgrade request

Throws:

Exception - if the WebSocket endpoint instance creation fails
