Overview
Primitives
Selector
A multiplexor that allows registration of multiple selectable channels so they can be serviced by a single selector thread. The selector thread will block in select() and it will be notified by the selector's implementation only when an I/O event, such as data becoming available or a new connection being established, occurs.
Channel
Selectable channel.
ServerSocketChannel
A selectable channel used to listen for incoming network connection and create new SocketChannels. The ServerSocketChannel delegates to a ServerSocket to do the actual listening.
SocketChannel
Buffer
Java NIO and TCP Connections
A working example that shows various Java NIO primitives collaborating in establishing a bidirectional TCP connection:
