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/Registry.java b/src/main/java/org/bukkit/Registry.java index 800d23bb249e19d5cf924e7ba36684068624da02..57e97b424cebd205cb260556ab9fb9eb2ff1eebc 100644 --- a/src/main/java/org/bukkit/Registry.java +++ b/src/main/java/org/bukkit/Registry.java @@ -307,6 +307,49 @@ public interface Registry extends Iterable { @Nullable T get(@NotNull NamespacedKey key); + // Paper start - improve Registry + /** + * Gets the key for this object or throws if it doesn't exist. + *
