OutputSocketChannelContext

public OutputSocketChannelContext(java.nio.channels.SocketChannel socketChannel,
                                  NioClient nioClient)
                           throws java.net.SocketException

Constructor to use on server socket channel

Parameters:

socketChannel - The socket channel on which a context must be created.

nioClient - The NIO Client agent using this output socket context

Throws:

java.net.SocketException

Method Detail

offer

public final boolean offer(byte[] buffer)

Add the data to send to a queue waiting its send.

Parameters:

buffer - The data to send.

Returns:

true if data have been correctly added to the queue; false if no more space in the queue.

write

public final void write(java.nio.channels.SelectionKey key)

This method is called by the NIO selector to write available data on the socket channel. If needed, data are cut in several packet to be multiplexed into the NIO selector and to use the same direct byte buffer.

Parameters:

key -

onClose

public final void onClose(java.nio.channels.SelectionKey key)
