    • onHeaders

      public void onHeaders(Metadata headers)
      Description copied from class: ClientCall.Listener
      The response headers have been received. Headers always precede messages.

      Since Metadata is not thread-safe, the caller must not access (read or write) headers after this point.

      Overrides:
      onHeaders in class PartialForwardingClientCallListener<RespT>
      Parameters:
      headers - containing metadata sent by the server at the start of the response.

    • onClose

      public void onClose(Status status, Metadata trailers)
      Description copied from class: ClientCall.Listener
      The ClientCall has been closed. Any additional calls to the ClientCall will not be processed by the server. No further receiving will occur and no further notifications will be made.

      Since Metadata is not thread-safe, the caller must not access (read or write) trailers after this point.

      If status returns false for Status.isOk(), then the call failed. An additional block of trailer metadata may be received at the end of the call from the server. An empty Metadata object is passed if no trailers are received.

      This method should not throw. If this method throws, there is no way to be notified of the exception. Implementations should therefore be careful of exceptions which can accidentally leak resources.

      Overrides:
      onClose in class PartialForwardingClientCallListener<RespT>
      Parameters:
      status - the result of the remote call.
      trailers - metadata provided at call completion.
