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.
