🦉 Event Bus 🦉

It is sometimes useful to use a Bus to communicate informations between various parts of the code. Owl has a very simple bus class, which manages subscriptions, triggering events, and callbacks.

const bus = new owl.core.EventBus();

bus.on("some-event", null, function (...args) {
  console.log(...args);
});

bus.trigger("some-event", 1, 2, 3);
// [1,2,3] will be logged to the console

Its API is:

Method	Description
`on(eventType, owner, callback)`	add a listener
`off(eventType, owner)`	remove all listeners for an owner
`trigger(eventType, ...args)`	trigger an event
`clear`	remove all subscriptions

Note that the Store is an example of an EventBus.
