Primitives

Selector

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.
