本文整理了Java中java.net.Socket.getChannel()方法的一些代码示例,展示了Socket.getChannel()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台,是从一些精选项目中提取出来的代码,具有较强的参考意义,能在一定程度帮忙到你。Socket.getChannel()方法的具体详情如下:
包路径:java.net.Socket
类名称:Socket
方法名:getChannel

Socket.getChannel介绍

[英]Returns this socket's SocketChannel, if one exists. A channel is available only if this socket wraps a channel. (That is, you can go from a channel to a socket and back again, but you can't go from an arbitrary socket to a channel.) In practice, this means that the socket must have been created by java.nio.channels.ServerSocketChannel#accept or java.nio.channels.SocketChannel#open.
[中]返回此套接字的SocketChannel(如果存在)。仅当此套接字包装通道时,通道才可用。(也就是说,您可以从一个通道转到一个插座,然后再返回,但不能从任意插座转到一个通道。)实际上,这意味着套接字必须是由java创建的。尼奥。频道。ServerSocketChannel#接受或java。尼奥。频道。袜子通道#打开。
