getTag

@NotNull
public @NotNull ITag<V> getTag(@NotNull
 @NotNull TagKey<V> name)

Description copied from interface: ITagManager

Queries this tag manager for a tag with the given tag key. If it does not exist, this will create an empty tag and return it.

Specified by:

getTag in interface ITagManager<V>

See Also:

• ITagManager.isKnownTagName(TagKey)

getReverseTag

@NotNull
public @NotNull Optional<IReverseTag<V>> getReverseTag(@NotNull
 V value)

Description copied from interface: ITagManager

Queries a reverse tag for a given value from the forge registry linked to this tag manager. A reverse tag stores all tags that the given value is contained in.

Specified by:

getReverseTag in interface ITagManager<V>

Parameters:

value - A value currently registered to the forge registry linked to this tag manager

Returns:

A reverse tag for the given value, or an empty optional if the value is not registered

isKnownTagName

public boolean isKnownTagName(@NotNull
 @NotNull TagKey<V> name)

Description copied from interface: ITagManager

Checks whether the given tag key exists in this tag manager and is bound. Unlike ITagManager.getTag(TagKey), this method will not create the tag if it does not exist.

Specified by:

isKnownTagName in interface ITagManager<V>

See Also:

• ITag.isBound()

iterator

@NotNull
public @NotNull Iterator<ITag<V>> iterator()

Specified by:

iterator in interface Iterable<V>

stream

@NotNull
public @NotNull Stream<ITag<V>> stream()

Specified by:

stream in interface ITagManager<V>

Returns:

A stream of all tags stored in this tag manager, bound or unbound.

getTagNames

@NotNull
public @NotNull Stream<TagKey<V>> getTagNames()

Specified by:

getTagNames in interface ITagManager<V>

Returns:

A stream of all tag keys stored in this tag manager, bound or unbound.

createTagKey

@NotNull
public @NotNull TagKey<V> createTagKey(@NotNull
 @NotNull ResourceLocation location)

Description copied from interface: ITagManager

Creates a tag key based on the location and the forge registry linked to this tag manager. Custom registries can use DeferredRegister.createTagKey(ResourceLocation) to create tag keys before the tag manager is created.

Specified by:

createTagKey in interface ITagManager<V>

See Also:

• ITagManager.createOptionalTagKey(ResourceLocation, Set)
• DeferredRegister.createTagKey(ResourceLocation)

createOptionalTagKey

@NotNull
public @NotNull TagKey<V> createOptionalTagKey(@NotNull
 @NotNull ResourceLocation location,
 @NotNull
 @NotNull Set<? extends Supplier<V>> defaults)

Description copied from interface: ITagManager

Creates a tag key that will use the set of defaults if the tag is not loaded from any datapacks. Useful on the client side when a server may not provide a specific tag. Custom registries can use DeferredRegister.addOptionalTagDefaults(TagKey, Set) to create tag keys before the tag manager is created.

Specified by:

createOptionalTagKey in interface ITagManager<V>

See Also:

• ITagManager.createTagKey(ResourceLocation)
• ITagManager.addOptionalTagDefaults(TagKey, Set)
• DeferredRegister.createOptionalTagKey(ResourceLocation, Set)

addOptionalTagDefaults

public void addOptionalTagDefaults(@NotNull
 @NotNull TagKey<V> name,
 @NotNull
 @NotNull Set<? extends Supplier<V>> defaults)

Description copied from interface: ITagManager

Adds defaults to an existing tag key. The set of defaults will be bound to the tag if the tag is not loaded from any datapacks. Useful on the client side when a server may not provide a specific tag. Custom registries can use DeferredRegister.addOptionalTagDefaults(TagKey, Set) to add defaults before the tag manager is created.

Specified by:

addOptionalTagDefaults in interface ITagManager<V>

See Also:

• ITagManager.createOptionalTagKey(ResourceLocation, Set)
• DeferredRegister.addOptionalTagDefaults(TagKey, Set)
