@Immutable

public final class Empty
extends Object
implements Instance

Empty instance that does absolutely nothing on every pulse and reports nothing.

It is convenient to use this instance wrapper when you want to disable the execution of an entire rule, but don't want to loose the code. Consider it a way to comment out your code in a rule.
