Class DisposeAggregator

DisposeAggregator is a utility class that allows you to add multiple items and then dispose them all at once. You can add a function to call, an object with a dispose method, or an object with a Symbol.dispose method. To dispose all the items, call dispose or use the Symbol.dispose symbol.

For example,

const disposeAggregator = new DisposeAggregator();

const eventRelay = new EventRelay<string>();
disposeAggregator.add(eventRelay);

const eventRelay2 = disposeAggregator.add(new EventRelay<string>());

disposeAggregator.dispose();
console.log(eventRelay.disposed === true); // true
console.log(eventRelay2.disposed === true); // true
