Package net.minecraft.nbt

Class NbtOps

java.lang.Object
net.minecraft.nbt.NbtOps
All Implemented Interfaces:
com.mojang.serialization.DynamicOps<Tag>
public class NbtOps
extends Object
implements com.mojang.serialization.DynamicOps<Tag>
Used to handle Minecraft NBTs within dynamics for DataFixerUpper, allowing generalized serialization logic shared across different type of data structures. Use INSTANCE for the ops singleton.

For instance, dimension data may be stored as JSON in data packs, but they will be transported in packets as NBT. DataFixerUpper allows generalizing the dimension serialization logic to prevent duplicate code, where the NBT ops allow the DataFixerUpper dimension serialization logic to interact with Minecraft NBTs.

  • Field Details

    • INSTANCE

      public static final NbtOps INSTANCE
      An singleton of the NBT dynamic ops.

      This ops does not compress maps (replace field name to value pairs with an ordered list of values in serialization). In fact, since Minecraft NBT lists can only contain elements of the same type, this op cannot compress maps.
