CLASS net/minecraft/class_2378 net/minecraft/registry/Registry
	COMMENT A registry is used to register various in-game components. Almost all parts of the
	COMMENT game - from blocks, items, and entity types, to cat types, goat horn instruments,
	COMMENT and structure pools - are registered in registries. Registry system allows the game
	COMMENT to enumerate all known types of something, and to assign a unique identifier to each
	COMMENT of those. Therefore, registering an object in the registry plays a very important
	COMMENT role, and failure to register new instances of registerable object usually results
	COMMENT in a bug or even a crash.
	COMMENT
	COMMENT <h2 id="terms">Terminologies</h2>
	COMMENT <p>A <strong>registry</strong> is an object that holds the mapping between three things:
	COMMENT the string ID, the numeric ID, and the registered value. There are many registries
	COMMENT for different types of registerable objects, and a registry's type parameter indicates
	COMMENT the accepted type. For example, you register your {@link net.minecraft.block.Block} to {@code
	COMMENT Registry<Block>}. It's important to note that registries themselves are registered
	COMMENT in a "registry of registries", {@link Registries#ROOT}.
	COMMENT
	COMMENT <p>The <strong>string ID</strong>, usually just called "ID", is a human-readable
	COMMENT {@link Identifier} that uniquely identifies the registered value in a registry.
	COMMENT This should stay the same between two game versions, and is usually used for disk
	COMMENT storage.
	COMMENT
	COMMENT <p>The <strong>numeric ID</strong> or <strong>raw ID</strong> is an integer
	COMMENT assigned automatically by the registry to each registered value. This is not
	COMMENT guaranteed to stay the same between two game versions, and is usually used for
	COMMENT networking purposes.
	COMMENT
	COMMENT <p>The <strong>registered value</strong>, often just called "value" in the code,
	COMMENT is the value added to the registry. The registry's type parameter determines
	COMMENT the type of the registered value.
	COMMENT
	COMMENT <p>Each registered value can also be identified with a <strong>{@linkplain RegistryKey
	COMMENT registry key}</strong>. A registry key is a combination of the registry's ID and
	COMMENT the registered value's ID. Using a registry key makes the type of the ID's
	COMMENT associated value clear, as the type parameter contains the type.
	COMMENT
	COMMENT <p>A <strong>{@linkplain RegistryEntry registry entry}</strong> is an object
	COMMENT holding a value that can be registered in a registry. In most cases, the
	COMMENT value is already registered in a registry ("reference entry"), hence the name;
	COMMENT however, it is possible to create a registry entry by direct reference
	COMMENT ("direct entry"). This is useful for data packs, as they can define
	COMMENT one-time use values directly without having to register them every time.
	COMMENT
	COMMENT <p>A <strong>{@link RegistryEntryList registry entry list}</strong> is a list
	COMMENT of registry entries. This, is either a direct reference to each item, or
	COMMENT a reference to a tag. A <strong>tag</strong> is a way to dynamically
	COMMENT define a list of registered values. Anything registered in a registry
	COMMENT can be tagged, and each registry holds a list of tags it recognizes.
	COMMENT
	COMMENT <h2 id="static-and-dynamic-registries">Static and dynamic registries</h2>
	COMMENT <p>There are two kinds of registries: static and dynamic.
	COMMENT
	COMMENT <ul>
	COMMENT <li>A <strong>static registry</strong> is a registry whose values are hard-coded
	COMMENT in the game and cannot be added or modified through data packs. Most registries
	COMMENT are static. Since they cannot be modified (without mods), it is a singleton,
	COMMENT and exists in this class. During the game bootstrap, vanilla objects are
	COMMENT registered, after which the registry gets frozen to prohibit further changes.</li>
	COMMENT
	COMMENT <li>A <strong>dynamic registry</strong> is a registry whose values can be
	COMMENT added or replaced through data packs. A dynamic registry is bound to a server,
	COMMENT and multiple registries for the same type of registerable object can exist during
	COMMENT the lifetime of the game. When a player joins, the server sends the contents of
	COMMENT the dynamic registry manager to the client, but only "network serializable"
	COMMENT registries are sent. To access a dynamic registry, first get an instance of the
	COMMENT dynamic registry manager, then call the {@link DynamicRegistryManager#get} method.</li>
	COMMENT </ul>
	COMMENT
	COMMENT <h2 id="using">Using Registry</h2>
	COMMENT <h3 id="reading">Reading Registry</h3>
	COMMENT <p>A registry is also an {@link IndexedIterable}. Therefore, registries can be
	COMMENT iterated using, e.g. {@code for (Block block : Registries.BLOCK)}.
	COMMENT
	COMMENT <p>There are several other methods used for reading the contents of the registry:
	COMMENT <ul>
	COMMENT <li>{@link #entryOf} or {@link #getEntry(RegistryKey)} for getting the registry entry
	COMMENT from the key.</li>
	COMMENT <li>{@link #get(Identifier)} or {@link #get(RegistryKey)} for getting the registered
	COMMENT value from the ID or the registry key.</li>
	COMMENT <li>{@link #getId(Object)} for getting the ID of a registered value.</li>
	COMMENT <li>{@link #getEntry(int)} for getting the registry entry from the raw ID.</li>
	COMMENT <li>{@link #getEntryList} and {@link #iterateEntries} for getting the contents of a tag,</li>
	COMMENT <li>{@link #streamTags} for streaming all tags of a registry.</li>
	COMMENT </ul>
	COMMENT
	COMMENT <h3 id="registering">Registering something to Registry</h3>
	COMMENT <p>The steps for registration are different, depending on whether the registry is static
	COMMENT or dynamic. For dynamic registries, data packs can usually be used to register a new
	COMMENT value or replace one. For static registries, the game's code must be modified.
	COMMENT
	COMMENT <p>Static registries are defined in {@link Registries}, and unlike the dynamic registries, it
	COMMENT cannot be changed after the game initialization. The game enforces this by "freezing"
	COMMENT the registry. Attempting to register a value after freezing causes a crash, such as
	COMMENT "Registry is already frozen". Modding APIs usually provide a way to bypass this restriction.
	COMMENT
	COMMENT <p>Use {@link #register(Registry, Identifier, Object)} for registering a value to a registry.
	COMMENT
	COMMENT <h3 id="intrusive-holders">Intrusive holders</h3>
	COMMENT <p>For historical reasons, there are two types of reference registry entries.
	COMMENT (This is different from the "direct" and "reference" registry entry types.)
	COMMENT
	COMMENT <ul>
	COMMENT <li><strong>Intrusive holders</strong> are registry entries tied to a specific
	COMMENT registerable object at instantiation time. When instantiating those, it promises
	COMMENT that the object is later registered - which, if broken, will result in a crash.
	COMMENT This is used for {@link Registries#BLOCK}, {@link Registries#ITEM}, {@link Registries#FLUID},
	COMMENT {@link Registries#ENTITY_TYPE}, and {@link Registries#GAME_EVENT} registries.</li>
	COMMENT <li><strong>Standalone holders</strong> are registry entries that are not intrusive.
	COMMENT There is no restriction on instantiation.</li>
	COMMENT </ul>
	COMMENT
	COMMENT <p>When a class whose instances are registered as intrusive holders, such as
	COMMENT {@link net.minecraft.block.Block} or {@link net.minecraft.item.Item}, are instantiated
	COMMENT without registering, the game crashes with "Some intrusive holders were not added to
	COMMENT registry" error message. <strong>This includes conditional registration</strong>.
	COMMENT For example, the code below can cause a crash:
	COMMENT
	COMMENT <pre>{@code
	COMMENT Item myItem = new Item(new Item.Settings());
	COMMENT if (condition) {
	COMMENT     Registry.register(Registries.ITEM, new Identifier("example", "bad"), myItem);
	COMMENT }
	COMMENT }</pre>
	COMMENT
	COMMENT <p>The correct way is to make the instantiation conditional as well:
	COMMENT
	COMMENT <pre>{@code
	COMMENT if (condition) {
	COMMENT     Item myItem = new Item(new Item.Settings());
	COMMENT     Registry.register(Registries.ITEM, new Identifier("example", "bad"), myItem);
	COMMENT }
	COMMENT }</pre>
