@ParametersAreNonnullByDefault
public final class TagCache
extends Object

Manages information sent from the ClientboundUpdateTagsPacket. If that packet is not sent, all lists here will remain empty, matching Java Edition behavior. Looking up a tag that wasn't listed in that packet will return an empty array. Only tags from suitable registries in JavaRegistries are stored. Read JavaRegistryKey for more information.
