Interface KeySet<T>

Type Parameters:

T - the type of the entries

@NonExtendable
public interface KeySet<T>

A set of registry entries, either a tag or an explicit list of keys, as data packs declare it.

Resolving a tag requires the server registries: use Enchantments.isSupportedItem(TypedKey, TypedKey) or Enchantments.areCompatible(TypedKey, TypedKey) to test membership.
