Adds an IObservableDisposable interface on top of IDisposable to help keep track of disposal status and trigger an event when an object is disposed.
public class Example : IObservableDisposable
{
public bool IsDisposed { get; private set; }
public event DisposalEvent? OnDispose;
private readonly SomeDisposableThingy _thingy;
public Example(SomeDisposableThingy thingy)
{
_thingy = thingy;
}
public void Dispose()
{
//You probably don't want to trigger this event multiple times for the same object
if (!IsDisposed)
{
//You may want to manually unsubscribe this event on listeners after this to ensure proper disposal
OnDispose?.Invoke(this);
IsDisposed = true;
//Spoiler alert : No, you don't need to do _thingy = null;
_thingy.Dispose();
}
}
