本文整理了Java中io.netty.channel.epoll.Epoll.isAvailable()方法的一些代码示例，展示了Epoll.isAvailable()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。Epoll.isAvailable()方法的具体详情如下：
包路径：io.netty.channel.epoll.Epoll
类名称：Epoll
方法名：isAvailable

Epoll.isAvailable介绍

[英]Returns true if and only if the netty-transport-native-epoll is available.
[中]当且仅当netty-transport-native-epoll可用时返回true。
