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/MusicInstrument.java b/src/main/java/org/bukkit/MusicInstrument.java index 62d2b3f950860dee0898d77b0a29635c3f9a7e23..704dba92f9246ef398ed8d162ebee3cf305960e1 100644 --- a/src/main/java/org/bukkit/MusicInstrument.java +++ b/src/main/java/org/bukkit/MusicInstrument.java @@ -53,6 +53,16 @@ public abstract class MusicInstrument implements Keyed, net.kyori.adventure.tran return instrument; } + // Paper start - deprecate getKey + /** + * @deprecated use {@link Registry#getKey(Keyed)} and {@link Registry#INSTRUMENT}.
