Interface RegistryHasher<DirectType>

Type Parameters:
DirectType - the type this hasher hashes. Only used for registry hashers that can hash holders.
All Superinterfaces:
MinecraftHasher<Integer>
All Known Implementing Classes:
RegistryHasher.RegistryHasherWithDirectHasher
public interface RegistryHasher<DirectType> extends MinecraftHasher<Integer>
RegistryHashers are hashers that hash a network integer ID to a namespaced identifier. RegistryHashers can be created using static utility methods in this class, and all registry hashers should be kept in here.

The RegistryHasher parameter is only used for registry hashers that are able to encode Holders, and must be left as a ? if this functionality is not in use. This makes it clear the hasher is not supposed to be able to encode holders.

To create a hasher that can encode a Holder, a direct hasher should be created that hashes a RegistryHasher (in case of a custom holder), and registry(JavaRegistryKey, MinecraftHasher) should be used to create the registry hasher. holder() can then be used to obtain a hasher that encodes a holder of RegistryHasher.

Along with RegistryHashers, this class also contains a bunch of hashers for various Minecraft objects. For organisational purposes, these are grouped in various sections with comments.

  • Method Details

    • registry

      static RegistryHasher<?> registry(JavaRegistryKey<?> registry)
      Creates a hasher that uses the JavaRegistryKey.keyFromNetworkId(GeyserSession, int) method to turn a network ID into a Key, and then encodes this key.
      Parameters:
      registry - the registry to create a hasher for.

    • registry

      static <DirectType> RegistryHasher<DirectType> registry(JavaRegistryKey<?> registry, MinecraftHasher<DirectType> directHasher)
      Creates a hasher that encodes network IDs using registry(JavaRegistryKey), and is also able to encode Holders by using the directHasher.

      A hasher that encodes Holders can be obtained by using holder()

      Type Parameters:
      DirectType - the type of custom objects.
      Parameters:
      registry - the registry to create a hasher for.
      directHasher - the hasher that encodes a custom object.
      See Also:

    • holder

      default MinecraftHasher<org.geysermc.mcprotocollib.protocol.data.game.Holder<DirectType>> holder()
      Creates a hasher that encodes a Holder of RegistryHasher. If the holder has an ID, the RegistryHasher is used to encode it. If the holder is custom, a direct hasher specified in registry(JavaRegistryKey, MinecraftHasher) is used to encode it.

      This method can only be used if this hasher has a direct hasher attached to it. That is only the case if RegistryHasher is not ?. If this hasher doesn't have a direct hasher, a IllegalStateException will be thrown upon use.

      Throws:
      IllegalStateException - when this hasher does not have a direct hasher attached to it.

    • holderSet

      default MinecraftHasher<org.geysermc.mcprotocollib.protocol.data.game.item.component.HolderSet> holderSet()
      Creates a hasher that hashes a HolderSet of the registry. HolderSets can encode as a hash-prefixed tag, a single namespaced ID, or a list of namespaced IDs.

      The hasher throws a IllegalStateException if the holder set does not have a tag nor a list of IDs. This should never happen.

    • enumRegistry

      static <EnumConstant extends Enum<EnumConstant>> MinecraftHasher<EnumConstant> enumRegistry()
      Creates a hasher that uses Enum.name() (lowercased) to create a key in the minecraft namespace, and then hashes it.

      Please be aware that you are using literal enum constants as key paths here, meaning that if there is a typo in a constant, or a constant changes name, things may break. Use cautiously.

      Type Parameters:
      EnumConstant - the enum.

    • enumIdRegistry

      static <EnumConstant extends Enum<EnumConstant>> RegistryHasher<?> enumIdRegistry(EnumConstant[] values)
      Uses Enum.name() (lowercased) to create a function that creates a Key from a RegistryHasher, and uses this as toKey function in enumIdRegistry(Enum[], Function).

      Please be aware that you are using literal enum constants as key paths here, meaning that if there is a typo in a constant, or a constant changes name, things may break. Use cautiously.

      Type Parameters:
      EnumConstant - the enum.
      Parameters:
      values - the array of RegistryHashers.
      See Also:

    • enumIdRegistry

      static <EnumConstant extends Enum<EnumConstant>> RegistryHasher<?> enumIdRegistry(EnumConstant[] values, Function<EnumConstant,net.kyori.adventure.key.Key> toKey)
      Creates a hasher that looks up a network ID in the array of RegistryHashers, and then uses toKey to turn the constant into a key, which it then hashes.
      Type Parameters:
      EnumConstant - the enum.
      Parameters:
      values - the array of RegistryHashers.
      toKey - the function that turns a RegistryHasher into a Key.
