本文整理了Java中io.vertx.core.Context.isOnWorkerThread()方法的一些代码示例，展示了Context.isOnWorkerThread()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。Context.isOnWorkerThread()方法的具体详情如下：
包路径：io.vertx.core.Context
类名称：Context
方法名：isOnWorkerThread

Context.isOnWorkerThread介绍

[英]Is the current thread a worker thread?

NOTE! This is not always the same as calling Context#isWorkerContext. If you are running blocking code from an event loop context, then this will return true but Context#isWorkerContext will return false.
[中]当前线程是工作线程吗？
笔记这并不总是与调用上下文#isWorkerContext相同。如果您正在从事件循环上下文运行阻塞代码，那么这将返回true，但context#isWorkerContext将返回false。
