Ember.run.join()

If no run-loop is present, it creates a new one. If a run loop is present it will queue itself to run on the existing run-loops action queue.

Please note: This is not for normal usage, and should be used sparingly.

If invoked when not within a run loop:

run.join(function() {
  // creates a new run-loop
});

Alternatively, if called within an existing run loop:

run(function() {
  // creates a new run-loop
  run.join(function() {
    // joins with the existing run-loop, and queues for invocation on
    // the existing run-loops action queue.
  });
});
