Timer Functions

.start()

Stop the timer

<button ng-click="AppTimer.start()"> Start </button>

.stop()

Starting/Resuming the timer.

<button ng-click="AppTimer.start()"> Start </button>

.restart()

Restart the timer with the values given when creating the timer. Timer won't start running, need to use start()

<button ng-click="AppTimer.restart()"> Restart </button>

.update()

Update one of the parameters given to the new CountDownTimer()'s properties ( id, counter etc .. ) The update action will save the values into LocalStorage as well, but won't restart the timer. Timer won't start running, need to use start()

<button ng-click="AppTimer.update('counter', 120)"> Update </button>

Timer Information

.getCounter()

Will return the exiting counter value

$scope.counter = $scope.AppTimer.getCounter();

.getLastUpdate()

Will return the "last updated" value that the timer has stored. The value is a Date() object.

$scope.lastUpdate = $scope.AppTimer.getLastUpdate();

.getInfo()

Return as JSON all the possible information stored in LocalStorage. Meaning the counter, last_updated, the timer's id etc ..

$scope.counter = $scope.AppTimer.getCounter();

Timer LocalStorage Actions

.reload()

So the reload() isn't really there ... we need to write it on our own in our controller as: If $scope.properties.id - is already found in LocalStorage - the timer will be reloaded with the last counter. But if the id isn't found, it will create a new timer.

    $scope.reload = function() {
        $scope.AppTimer = new CountDownTimer($scope.properties);
        update_timer_info();
    }

.remove()

Removing the timer entirly from LocalStorage. Remember that in order to continue from where we left off - the timer is always there ...

$scope.AppTimer.remove();
