Interface ITimerHandler

enabled

let theTimer = createTimeout(...);

// Check if enabled
theTimer.enabled; // false

// Start the timer
theTimer.enabled = true;     // Same as calling refresh()
theTimer.enabled; //true

// Has no effect as it's already running
theTimer.enabled = true;

// Will refresh / restart the time
theTimer.refresh()

let theTimer = scheduleTimeout(...);

// Check if enabled
theTimer.enabled; // true
Copy

cancel

• cancel(): void

• Cancels a timeout that was previously scheduled, after calling this function any previously scheduled timer will not execute.

  Returns void

  Example

  let theTimer = scheduleTimeout(...);
  theTimer.cancel();
  Copy

hasRef

• hasRef(): boolean

• If true, any running referenced ITimerHandler instance will keep the Node.js event loop active.

  Returns boolean

  Since

  0.7.0

  Example

  let theTimer = createTimeout(...);
  
  // Unreference the timer so that the runtime (Node) may terminate if nothing else is running.
  theTimer.unref();
  let hasRef = theTimer.hasRef(); // false
  
  theTimer.ref();
  hasRef = theTimer.hasRef(); // true
  Copy

ref

• ref(): this

• When called, requests that the event loop not exit so long when the ITimerHandler is active. Calling timer.ref() multiple times will have no effect. By default, all ITimerHandler objects will create "ref'ed" instances, making it normally unnecessary to call timer.ref() unless timer.unref() had been called previously.

  Returns this

  the ITimerHandler instance

  Since

  0.7.0

  Example

  let theTimer = createTimeout(...);
  
  // Make sure the timer is referenced (the default) so that the runtime (Node) does not terminate
  // if there is a waiting referenced timer.
  theTimer.ref();
  Copy

refresh

• refresh(): ITimerHandler

• Reschedules the timer to call its callback at the previously specified duration adjusted to the current time. This is useful for refreshing a timer without allocating a new JavaScript object.

  Using this on a timer that has already called its callback will reactivate the timer. Calling on a timer that has not yet executed will just reschedule the current timer.

  Returns ITimerHandler

  Example

  let theTimer = scheduleTimeout(...);
  // The timer will be restarted (if already executed) or rescheduled (if it has not yet executed)
  theTimer.refresh();
  Copy

unref

• unref(): this

• When called, the any active ITimerHandler instance will not require the event loop to remain active (Node.js). If there is no other activity keeping the event loop running, the process may exit before the ITimerHandler instance callback is invoked. Calling timer.unref() multiple times will have no effect.

  Returns this

  the ITimerHandler instance

  Since

  0.7.0

  Example

  let theTimer = createTimeout(...);
  
  // Unreference the timer so that the runtime (Node) may terminate if nothing else is running.
  theTimer.unref();
