Dispatching Event

To dispatch event:

aggregator.get('some event').dispatch(args, noListenersCallback, enqueuedCallback);

In which:

• args is an object that provides arguments for event listeners.

• noListenerCallback is a callback function that will be invoked if there is no listeners listening to the specified event. This function accepts no parameters.

• enqueuedCallback is in constrast to noListenerCallback, will be invoked when there is at least one listener and the event is about to be dispatched. This function accepts no parameters.

Below is an example:

aggregator.get('Price Changed').dispatch(12.00, () => {
    console.log('No listeners');
}, () => {
    console.log('Event enqueued');
})
