Constructor Detail

AbstractNioByteChannel

protected AbstractNioByteChannel(Channel parent,
                      SelectableChannel ch)

Create a new instance

Parameters:

parent - the parent Channel by which this instance was created. May be null

ch - the underlying SelectableChannel on which it operates

Method Detail

newUnsafe

Description copied from class: AbstractChannel

Create a new AbstractChannel.AbstractUnsafe instance which will be used for the life-time of the Channel

Specified by:

newUnsafe in class AbstractChannel

doWrite

protected void doWrite(ChannelOutboundBuffer in)
                throws Exception

Description copied from class: AbstractChannel

Flush the content of the given buffer to the remote peer.

Specified by:
