public interface Cancellable
Events that implement this interface are cancellable, i.e they can be cancelled by a plugin. Cancelling an event usually means that it will no longer be executed. Other event listeners will still receive the event, but the game won't process the action anymore. For example, when cancelling the event that the player gets damage (PlayerDamageEvent), the player actually won't get damage.

An event is considered cancelled if the setCancelled(boolean) method was called with a true parameter. Please note that another event listener may revert this again by calling the method with a false parameter.
