      Gets a codec that encodes an enum as a string.

    • extend

      public static <M, E> com.mojang.serialization.Codec<com.mojang.datafixers.util.Pair<M,E>> extend(com.mojang.serialization.Codec<M> codec, com.mojang.serialization.MapCodec<E> extension)
      Extends the give Codec with some new fields defined by the given MapCodec. The given codec must encode to a MapLike.

      Extends the give Codec with some new fields defined by the given MapCodec. The given codec must encode to a MapLike.

    • mapDispatch

      public static <A, K, V> com.mojang.serialization.Codec<A> mapDispatch(com.mojang.serialization.MapCodec<K> keyCodec, Function<K,com.mojang.serialization.DataResult<com.mojang.serialization.Codec<? extends V>>> valueCodecs, Function<A,com.mojang.datafixers.util.Pair<K,V>> decompose, BiFunction<K,V,com.mojang.serialization.DataResult<A>> construct)
      Creates a map dispatched codec. When encoding an element, it ist first decomposed into key and value. The key is used to obtain a codec to encode the value using the passed valueCodecs function. The Codec returned from that function must encode to a MapLike. After that, the key is encoded and merged into the MapLike from the value codec. Decoding works the other way round in that the key is read first. Then the valueCodecs function is used to obtain a Codec to decode the value. In the end, the codec uses both key and value to construct the resulting element. Both the MapCodec and the codecs returned from valueCodecs must be able to work with additional values, they don't know about.

    • lazy

      public static <T> com.mojang.serialization.Codec<T> lazy(Supplier<com.mojang.serialization.Codec<T>> codec)
      Lazily wraps the given Codec. Useful when codecs need to reference each other to recurse.

    • optionalFieldOf

      public static <T> com.mojang.serialization.MapCodec<Optional<T>> optionalFieldOf(com.mojang.serialization.Codec<T> codec, String name)
      Behaves the same as Codec.optionalFieldOf(String) but instead of silently using the default value if decoding the element produces an error, propagates the error through. The only way this yields an empty Optional is if the key is completely missing.

    • optionalFieldOf

      public static <T> com.mojang.serialization.MapCodec<T> optionalFieldOf(com.mojang.serialization.Codec<T> codec, String name, T defaultValue)
      Behaves the same as Codec.optionalFieldOf(String, Object) but instead of silently using the default value if decoding the element produces an error, propagates the error through. The only way this yields an empty Optional is if the key is completely missing.

    • typeMapped

      @SafeVarargs public static <T> com.mojang.serialization.Codec<T> typeMapped(TypedEncoder<T,?>... encoders)
      Gets a type mapped codec that will try to encode and decode values with the first matching TypedEncoder. If no TypedEncoder matches, an error will be returned.

    • typeMapped

      @SafeVarargs public static <T> com.mojang.serialization.Codec<T> typeMapped(com.mojang.serialization.Codec<T> fallback, TypedEncoder<T,?>... encoders)
      Gets a type mapped codec that will try to encode and decode values with the first matching TypedEncoder. If no TypedEncoder matches, the fallback is used.
