class FSWatcher

Alias for emitter.on(eventName, listener).

See also:

• https://nodejs.org/api/events.html#events_emitter_addlistener_eventname_listener

Synchronously calls each of the listeners registered for the event named eventName, in the order they were registered, passing the supplied arguments to each.

See also:

• https://nodejs.org/api/events.html#events_emitter_emit_eventname_args

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

See also:

• https://nodejs.org/api/events.html#events_emitter_eventnames

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

See also:

• https://nodejs.org/api/events.html#events_emitter_getmaxlisteners

Returns the number of listeners listening to the event named eventName.

See also:

• https://nodejs.org/api/events.html#events_emitter_listenercount_eventname

Returns a copy of the array of listeners for the event named eventName.

See also:

• https://nodejs.org/api/events.html#events_emitter_listeners_eventname

Alias for emitter.removeListener().

See also:

• https://nodejs.org/api/events.html#events_emitter_off_eventname_listener

Adds the listener function to the end of the listeners array for the event named eventName. No checks are made to see if the listener has already been added. Multiple calls passing the same combination of eventName and listener will result in the listener being added, and called, multiple times.

See also:

• https://nodejs.org/api/events.html#events_emitter_on_eventname_listener

Adds a one-time listener function for the event named eventName. The next time eventName is triggered, this listener is removed and then invoked.

See also:

• https://nodejs.org/api/events.html#events_emitter_once_eventname_listener

Adds the listener function to the beginning of the listeners array for the event named eventName. No checks are made to see if the listener has already been added. Multiple calls passing the same combination of eventName and listener will result in the listener being added, and called, multiple times.

See also:

• https://nodejs.org/api/events.html#events_emitter_prependlistener_eventname_listener

Adds a one-time listener function for the event named eventName to the beginning of the listeners array. The next time eventName is triggered, this listener is removed, and then invoked.

See also:

• https://nodejs.org/api/events.html#events_emitter_prependoncelistener_eventname_listener

Returns a copy of the array of listeners for the event named eventName, including any wrappers (such as those created by .once()).

See also:

• https://nodejs.org/api/events.html#events_emitter_rawlisteners_eventname

Removes all listeners, or those of the specified eventName.

See also:

• https://nodejs.org/api/events.html#events_emitter_removealllisteners_eventname

Removes the specified listener from the listener array for the event named eventName.

See also:

• https://nodejs.org/api/events.html#events_emitter_removelistener_eventname_listener

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. Obviously, not all events should be limited to just 10 listeners. 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.
