Interface RedstoneOutputEvent

All Superinterfaces:
Cancellable, Event, RedstoneEvent
public interface RedstoneOutputEvent extends RedstoneEvent, Cancellable
Fired when a redstone component is about to change the signal it emits: a lever pulled, a button pressed or popping back out, a torch turning on or off, a repeater or a comparator switching, an observer pulsing.

The signals are those the component emits towards the blocks it powers: 15 or 0 for most components, the level it outputs for a comparator.

Cancelling the event keeps the component as it is, and the blocks around it are not told anything changed. A lever stays where it was. A button is not pressed, or, popping back out, stays pressed and tries again once its delay has elapsed once more; an observer ending its pulse tries again two game ticks later. A repeater, a comparator or a torch tries again when one of its neighbours next changes.
