Class Empty

java.lang.Object

me.lucko.helper.metadata.Empty

public final class Empty
extends Object

An object which represents nothing.

Used mostly by MetadataKeys, where the presence of the key in the map is enough for a behaviour to apply. In other words, the value is not significant.

Very similar to Void, except this class also provides an instance of the "empty" object.
