Constructor Detail

AbstractNonblockingServer

public AbstractNonblockingServer(AbstractNonblockingServer.AbstractNonblockingServerArgs args)

Method Detail

serve

public void serve()

Begin accepting connections and processing invocations.

Specified by:

serve in class TServer

startThreads

protected abstract boolean startThreads()

Starts any threads required for serving.

Returns:

true if everything went ok, false if threads could not be started.

waitForShutdown

protected abstract void waitForShutdown()

A method that will block until when threads handling the serving have been shut down.

startListening

protected boolean startListening()

Have the server transport start accepting connections.

Returns:

true if we started listening successfully, false if something went wrong.

stopListening

protected void stopListening()

Stop listening for connections.

requestInvoke

protected abstract boolean requestInvoke(AbstractNonblockingServer.FrameBuffer frameBuffer)

Perform an invocation. This method could behave several different ways - invoke immediately inline, queue for separate execution, etc.

Returns:

true if invocation was successfully requested, which is not a guarantee that invocation has completed. False if the request failed.
