      Description copied from interface: `javax.websocket.RemoteEndpoint`
      Enable or disable the batching of outgoing messages for this endpoint. If batching is disabled when it was previously enabled then this method will block until any currently batched messages have been written.

    - #### getBatchingAllowed

          public boolean getBatchingAllowed()

      Description copied from interface: `javax.websocket.RemoteEndpoint`

      Specified by:
        `getBatchingAllowed` in interface `RemoteEndpoint`
      Returns:
        `true` if batching is enabled, otherwise `false`.
