Constructor Details

NioDatagramWorker

NioDatagramWorker(Executor executor)

Sole constructor.

Parameters:

executor - the Executor used to execute Runnables such as NioDatagramWorker.ChannelRegistionTask

Method Details

read

protected boolean read(SelectionKey key)

Description copied from class: AbstractNioWorker

Read is called when a Selector has been notified that the underlying channel was something to be read. The channel would previously have registered its interest in read operations.

Specified by:

read in class AbstractNioWorker

Parameters:

key - The selection key which contains the Selector registration information.

scheduleWriteIfNecessary

protected boolean scheduleWriteIfNecessary(AbstractNioChannel<?> channel)

Specified by:

scheduleWriteIfNecessary in class AbstractNioWorker

disconnect

static void disconnect(NioDatagramChannel channel,
 ChannelFuture future)

createRegisterTask

protected Runnable createRegisterTask(Channel channel,
 ChannelFuture future)

Specified by:

createRegisterTask in class AbstractNioSelector

writeFromUserCode

public void writeFromUserCode(AbstractNioChannel<?> channel)

Overrides:

writeFromUserCode in class AbstractNioWorker

write0

protected void write0(AbstractNioChannel<?> channel)

Overrides:

write0 in class AbstractNioWorker

run

public void run()

Specified by:

run in interface Runnable

Overrides:

run in class AbstractNioWorker
