Examples of net.spy.memcached.ops.OperationCallback

net.spy.memcached.ops.OperationCallback
Callback that's invoked with the response of an operation.

        cb.receivedStatus(STATUS_OK);
        cb.complete();
      }
      transitionState(OperationState.COMPLETE);
    } else {
      OperationCallback cb = callbacks.remove(responseOpaque);
      assert cb != null : "No callback for " + responseOpaque;
      assert errorCode != 0 : "Got no error on a quiet mutation.";
      OperationStatus status=getStatusForErrorCode(errorCode, pl);
      assert status != null : "Got no status for a quiet mutation error";
      cb.receivedStatus(status);
      cb.complete();
    }
    resetInput();
