what is the Ember implementation of setInterval and clearInterval

I'm not aware of any equivalent, but I use such a code to have the functionality:

var Poller = Ember.Object.extend({

  _interval: 1000,
  _currentlyExecutedFunction: null,

  start: function(context, pollingFunction) {
    this.set('_currentlyExecutedFunction', this._schedule(context, pollingFunction, [].slice.call(arguments, 2)));
  },

  stop: function() {
    Ember.run.cancel(this.get('_currentlyExecutedFunction'));
  },

  _schedule: function(context, func, args) {
    return Ember.run.later(this, function() {
      this.set('_currentlyExecutedFunction', this._schedule(context, func, args));
      func.apply(context, args);
    }, this.get('_interval'));
  },

  setInterval: function(interval) {
    this.set('_interval', interval);
  }

});

export
default Poller;

Then, you instantiate the poller: var poller = Poller.create() and then you can play with poller.start() and poller.stop() + set set the interval via poller.setInterval(interval).

In my code, I did more or less that way (polling the reports every 10 seconds):

_updateRunningReport: function(report) {
  var poller = new Poller();
  poller.setInterval(this.POLLING_INTERVAL);
  poller.start(this, function() {
    if (report.isRunning()) {
      this._reloadReport(report);
    } else {
      poller.stop();
    }
  });
  eventBus.onLogout(function() {
    poller.stop();
  });
},

Hope this helps...
