Interface RegistryKeySet<T extends Keyed>

Type Parameters:

T - registry value type

All Superinterfaces:

Iterable<TypedKey<T>>, RegistrySet<T>

All Known Subinterfaces:

Tag<T>

@NonExtendable
public non-sealed interface RegistryKeySet<T extends Keyed>
extends Iterable<TypedKey<T>>, RegistrySet<T>

Represents a collection tied to a registry.

There are 2 types of registry key sets:

• Tag which is a tag from vanilla or a datapack. These are obtained via Registry.getTag(io.papermc.paper.registry.tag.TagKey).
• RegistryKeySet which is a set of keys linked to values that are present in the registry. These are created via RegistrySet.keySet(RegistryKey, Iterable) or RegistrySet.keySetFromValues(RegistryKey, Iterable).

Method Summary

Modifier and Type	Method	Description

@Unmodifiable Collection<T>	resolve(Registry<T> registry)	Resolve this set into a collection of values.
default int	size()	Get the size of this set.
@Unmodifiable Collection<TypedKey<T>>	values()	Get the keys for the values in this set.

size

default int size()

Description copied from interface: RegistrySet

Get the size of this set.

Specified by:

size in interface RegistrySet<T extends Keyed>

Returns:

the size

values

@Unmodifiable Collection<TypedKey<T>> values()

Get the keys for the values in this set.

Returns:

the keys

resolve

@Unmodifiable Collection<T> resolve(Registry<T> registry)

Resolve this set into a collection of values. Prefer using values().

Parameters:

registry - the registry to resolve the values from (must match RegistrySet.registryKey())

Returns:

the resolved values

contains

boolean contains(TypedKey<T> valueKey)

Checks if this set contains the value with the given key.

Parameters:

valueKey - the key to check

Returns:

true if the value is in this set
