Interface Evented<Events>

Base class which provides default on/emit functions to child classes.

Events are specified by providing a type or interface as a type parameter. The type parameter should list the supported event names and the event value type (or void if there is no value).

Example

interface MyEvents {
    numberChanged: number; // event handlers will receive a number value
    print: void;           // event handlers will receive no value
}

class MyClass extends Evented<MyEvents> {
// ...
}

const object = new MyClass();
object.on("numberChanged", (value) => {
   // value is a number
});
