Package net.minecraft.util.dynamic

Class Codecs

java.lang.Object
net.minecraft.util.dynamic.Codecs
public class Codecs extends Object
A few extensions for Codec or DynamicOps.

It has a few methods to create checkers for Codec.flatXmap to add extra value validation to encoding and decoding. See the implementation of nonEmptyList(Codec).

    • xor

      public static <F, S> com.mojang.serialization.Codec<com.mojang.datafixers.util.Either<F,S>> xor(com.mojang.serialization.Codec<F> first, com.mojang.serialization.Codec<S> second)
      Returns an exclusive-or codec for Either instances.

      This returned codec fails if both the first and second codecs can decode the input, while DFU's EitherCodec will always take the first decoded result when it is available.

      Otherwise, this behaves the same as the either codec.

      Type Parameters:
      F - the first type
      S - the second type
      Parameters:
      first - the first codec
      second - the second codec
      Returns:
      the xor codec for the two codecs
