Class EventRelay<T>

A simple event relay. Create a listener with createListener and dispatch events with dispatchEvent. For each supported event type, create a new instance of EventRelay and expose it as a property.

For example, this code:

class MyClass {
    public readonly onSomethingHappened = new EventRelay<string>();

    public doSomething(whatToDo: string) {
        this.onSomethingHappened.dispatchEvent(whatToDo);
        console.log("Done notifying listeners");
    }
}

const myClass = new MyClass();
myClass.onSomethingHappened.createListener((whatHappened) => {
    console.log(`Something happened: ${whatHappened}`);
});
myClass.doSomething("eat a cookie");
Copy

Will print this:

Something happened: eat a cookie
Done notifying listeners
Copy
