Class RegistryHolder<R,T extends R>

java.lang.Object

net.xun.lib.common.api.registries.RegistryHolder<R,T>

Type Parameters:

R - The base registry type (e.g. Item)

T - The concrete type of the held object (must extend R)

All Implemented Interfaces:

Supplier<T>, net.minecraft.core.Holder<R>, net.neoforged.neoforge.common.extensions.IHolderExtension<R>, net.neoforged.neoforge.registries.datamaps.IWithData<R>

Direct Known Subclasses:

RegistryBlock, RegistryItem

public class RegistryHolder<R,T extends R>
extends Object
implements net.minecraft.core.Holder<R>, Supplier<T>

A registry-backed holder implementation that wraps a registry entry and its supplier.

This class acts as a bridge between Holder and Supplier, allowing lazy initialization and late binding to actual registry entries.

RegistryHolder

protected RegistryHolder(net.minecraft.resources.ResourceKey<R> key,
 Supplier<T> supplier)

Creates a new RegistryHolder instance.

Parameters:

key - Resource key identifying the object in the registry

supplier - Supplier providing the concrete instance of the object

Method Details

create

public static <R,
T extends R> RegistryHolder<R,T> create(net.minecraft.resources.ResourceKey<R> key,
 Supplier<T> supplier)

getSupplier

public Supplier<T> getSupplier()
