Constructor Details

NioReceiver

public NioReceiver()

Method Details

stop

public void stop()

Description copied from interface: ChannelReceiver

Stop listening for messages

Specified by:

stop in interface ChannelReceiver

Overrides:

stop in class ReceiverBase

start

public void start()
           throws IOException

Start cluster receiver.

Specified by:

start in interface ChannelReceiver

Overrides:

start in class ReceiverBase

Throws:

IOException - If the receiver fails to start

See Also:

• ChannelReceiver.start()

createRxTask

public AbstractRxTask createRxTask()

Specified by:

createRxTask in interface RxTaskPool.TaskCreator

bind

protected void bind()
             throws IOException

Throws:

IOException

addEvent

public void addEvent(Runnable event)

events

public void events()

cancelledKey

public static void cancelledKey(SelectionKey key)

socketTimeouts

protected void socketTimeouts()

listen

protected void listen()
               throws Exception

Get data from channel and store in byte array send it to cluster

Throws:

IOException - IO error

Exception

stopListening

protected void stopListening()

Close Selector.

See Also:

• ReceiverBase.stop()

registerChannel

protected void registerChannel(Selector selector,
 SelectableChannel channel,
 int ops,
 Object attach)
                        throws Exception

Register the given channel with the given selector for the given operations of interest

Parameters:

selector - The selector to use

channel - The channel

ops - The operations to register

attach - Attachment object

Throws:

Exception - IO error with channel

run

public void run()

Start thread and listen

Specified by:

run in interface Runnable

readDataFromSocket

protected void readDataFromSocket(SelectionKey key)
                           throws Exception

Sample data handler method for a channel with data ready to read.

Parameters:

key - A SelectionKey object associated with a channel determined by the selector to be ready for reading. If the channel returns an EOF condition, it is closed here, which automatically invalidates the associated key. The selector will then de-register the channel on the next select call.

Throws:

Exception - IO error with channel
