From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Jake Potrebic Date: Wed, 20 Dec 2023 02:03:10 -0800 Subject: [PATCH] Improve Registry Adds Registry#getKey(Object) which should be the primary way people get the key for an object. Registry items need to exist without having a key and so getKey() methods on Keyed objects that have a registry are marked as Deprecated or Obsolete. diff --git a/src/main/java/org/bukkit/Art.java b/src/main/java/org/bukkit/Art.java index d24bf449f58fd7c1b8ffab8dbc42f9f1fef8c4ef..00a290f1bf58cdc2238c13fd5a6048a26b7871da 100644 --- a/src/main/java/org/bukkit/Art.java +++ b/src/main/java/org/bukkit/Art.java @@ -97,6 +97,16 @@ public interface Art extends OldEnum, Keyed { @Deprecated(since = "1.6.2") int getId(); + // Paper start - deprecate getKey + /** + * @deprecated use {@link Registry#getKey(Keyed)}, {@link io.papermc.paper.registry.RegistryAccess#getRegistry(io.papermc.paper.registry.RegistryKey)}, + * and {@link io.papermc.paper.registry.RegistryKey#PAINTING_VARIANT}.
