Add a convenient way to remove a listener inside itself.

It would be nice to have a method to remove a listener inside itself. This might be possible by overloading all registerXyzListener() with a method that accepts a BiConsumer that consumes both the event and the listener manager for this listener.

Oops, you are right ofc. But the “idea” keeps the same:

var listener ​=​ ​new​ ​AtomicReference<​MessageCreateListener​>​();
listener.set(event ​-​>​ {
  api​.​removeListener(listener​.​get());
});

api​.​addListener(listener​.​get());

Ah, right. Actually also the array variant should work without race condition and be marginally cheaper due to no need for volatile field and compare and swap algorithm as it is written before the other thread will read it and not modified.

var listener = new ​MessageCreateListener​[1];
listener[0] = e -> discordApi.removeListener(listener[0]);
discordApi.addMessageCreateListener(listener[0]);
