Examples with CloseReason javax.websocket.CloseReason used on opensource projects

Example 1 with CloseReason

use of javax.websocket.CloseReason in project jetty.project by eclipse.

the class AbstractJsrEventDriver method onClose.

@Override
public final void onClose(CloseInfo close) {

    CloseCode closecode = CloseCodes.getCloseCode(close.getStatusCode());
    CloseReason closereason = new CloseReason(closecode, close.getReason());
    onClose(closereason);
}

Example 2 with CloseReason
