            ext.setNextIncomingFrames(nextIncoming);
            nextIncoming = ext;
        }
    }
}

Example 7 with Extension

use of org.eclipse.jetty.websocket.api.extensions.Extension in project jetty.project by eclipse.

the class IdentityExtensionTest method testIncomingFrames.

/**

     */
@Test

    IncomingFramesCapture capture = new IncomingFramesCapture();
    Extension ext = new IdentityExtension();
    ext.setNextIncomingFrames(capture);
