Subject: [PATCH] Optimize Server World Map
|
|
|
|
Minecraft moved worlds to a hashmap in 1.13.1.
|
|
This creates inconsistent order for iteration of the map.
|
|
|
|
This patch restores World management to be back as an Array.
|
|
|
|
.values() will allow us to iterate as it was pre 1.13.1 by
|
|
ArrayList, giving consistent ordering and effecient iteration performance.
|
|
|
|
KeySet and EntrySet iteration is proxied to the List iterator,
|
|
and should retain manipulation behavior but nothing should be doing that.
|
|
|
|
Getting a World by dimension ID is now back a constant time operation.
|
|
|
|
Hopefully no other plugins try to mess with this map, as we are only handling
|
|
known NMS used methods, but we can add more if naughty plugins are found later.
