## Class WebSocketXMPPIOService<RefObject>

- java.lang.Object
- - tigase.net.IOService<RefObject>
  - - tigase.xmpp.XMPPIOService<RefObject>
    - - tigase.server.websocket.WebSocketXMPPIOService<RefObject>

- Type Parameters:
    `RefObject` -
  All Implemented Interfaces:
    Callable<IOService<?>>, TLSEventHandler, IOListener

      public class WebSocketXMPPIOService<RefObject>
      extends XMPPIOService<RefObject>

  Class implements basic support for WebSocket protocol. It extends XMPPIOService so it can be used instead of XMPPIOService in ClientConnectionManager to allow web clients to connect to it without using BOSH extension.
