immediate.unref()
- 返回: <Immediate>
immediate
的引用
调用时,活动的 Immediate
对象不需要 Node.js 事件循环保持活动状态。
如果没有其他活动保持事件循环运行,则进程可能会在调用 Immediate
对象的回调之前退出。
多次调用 immediate.unref()
将不起作用。
- Returns: <Immediate> a reference to
immediate
When called, the active Immediate
object will not require the Node.js event
loop to remain active. If there is no other activity keeping the event loop
running, the process may exit before the Immediate
object's callback is
invoked. Calling immediate.unref()
multiple times will have no effect.
