interface Immediate
This object is created internally and is returned from setImmediate(). It
can be passed to clearImmediate() in order to cancel the scheduled
actions.
By default, when an immediate is scheduled, the Node.js event loop will continue
running as long as the immediate is active. The Immediate object returned by
setImmediate() exports both immediate.ref() and immediate.unref()
functions that can be used to control this default behavior.
Methods #
When called, requests that the Node.js event loop not exit so long as the
Immediate is active. Calling immediate.ref() multiple times will have no
effect.
By default, all Immediate objects are "ref'ed", making it normally unnecessary
to call immediate.ref() unless immediate.unref() had been called previously.
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.
#[[Symbol.dispose]](): void Cancels the immediate. This is similar to calling clearImmediate().
#_onImmediate(...args: any[]): void
