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)

onError

protected void onError(Graph graph,
                       Context ctx,
                       Throwable error)

onTraversalSuccess

protected void onTraversalSuccess(Graph graph,
                                  Context ctx)

handleIterator

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

Throws:
