$timeout

1. - service in module ng

Angular's wrapper for window.setTimeout. The fn function is wrapped into a try/catch block and delegates any exceptions to $exceptionHandler service.

The return value of registering a timeout function is a promise, which will be resolved when the timeout is reached and the timeout function is executed.

To cancel a timeout request, call $timeout.cancel(promise).

In tests you can use $timeout.flush() to synchronously flush the queue of deferred functions.

$timeout(fn, [delay], [invokeApply]);
