|
||
|
||
<p>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.</p>
|
||
|
||
<p>To cancel a the timeout request, call <code>$timeout.cancel(promise)</code>.</p>

|
||
synchronously flush the queue of deferred functions.</p></div>
