  - ### Method Detail

    - #### getName

          public String getName()

      Description copied from interface: `OpProcessor`
      The name of the processor which requests must refer to "processor" field on a request.

    - #### close

          public void close()
                     throws Exception

      Throws:
        `Exception`

    - #### select

          public ThrowingConsumer<Context> select(Context context)
                                           throws OpProcessorException

      Description copied from interface: `OpProcessor`
      Given the context (which contains the RequestMessage), return back a Consumer function that will be executed with the context. A typical implementation will simply check the "op" field on the RequestMessage and return the Consumer function for that particular operation.
      Returns:
      Throws:
        `OpProcessorException`

    - #### beforeProcessing

          protected void beforeProcessing(Graph graph,

                                 Context ctx)

    - #### onTraversalSuccess

          protected void onTraversalSuccess(Graph graph,
                                            Context ctx)

    - #### handleIterator

          protected void handleIterator(Context context,
                                        Iterator itty,
                                        Graph graph)
                                 throws InterruptedException

      Throws:
        `InterruptedException`
