XNIO 介绍
XNIO是一个帮助你简化NIO应用程序开发的Java包。It frees you from the hassle of dealing with
Selectors and the lack of NIO support for multicast sockets and non-socket I/O
such as serial ports, while still maintaining all the capabilities present in
NIO. Also, XNIO vastly simplifies implementation of channels, opening the door
to supporting higer-level transport concepts (like SSL or virtual channels)
with the same simple API.
