FSWatcher

events.EventEmitter

Stop watching for changes on the given fs.FSWatcher. Once stopped, the fs.FSWatcher object is no longer usable.

Returns an array listing the events for which the emitter has registered listeners. The values in the array are strings or Symbols.

Returns the current max listener value for the EventEmitter which is either set by emitter.setMaxListeners(n) or defaults to {@link defaultMaxListeners}.

When called, requests that the Node.js event loop not exit so long as the fs.FSWatcher is active. Calling watcher.ref() multiple times will have no effect.

By default EventEmitters will print a warning if more than 10 listeners are added for a particular event. This is a useful default that helps finding memory leaks. The emitter.setMaxListeners() method allows the limit to be modified for this specific EventEmitter instance. The value can be set to Infinity (or 0) to indicate an unlimited number of listeners.

When called, the active fs.FSWatcher 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 fs.FSWatcher object's callback is invoked. Calling watcher.unref() multiple times will have no effect.
