Is there a way to store references to runnables?

Is there a way to store references to sync-runnables? I basically want to be able to start a runnable when an event fires, and be able to cancel it if another event fires. For example, start a runnable when a projectile hits a player. But if that player breaks a block, cancel the runnable. This is a pretty bad example, but that's the best way I can put it.

 

I suggest using BukkitRunnables and doing a check to see if something has happened (use a boolean) and use this.cancel().

 

Yes, you can, depending on what method you use you can either:
- store BukkitTask object returned from getScheduler().schedule*() methods
- store the class itself if it extends BukkitRunnable
Both of those have a cancel() method.
I also recommend using BukkitRunnable because it's easier, you can use cancel() and run*() directly on the class, and of course inside the class as well.

If you're storing them per player then a simple Map<String, BukkitRunnable or BukkitTask> would do.
