Package net.minecraft.world.chunk

Interface Palette<T>

All Known Implementing Classes:
ArrayPalette, BiMapPalette, IdListPalette, SingularPalette
public interface Palette<T>
A palette maps objects from and to small integer IDs that uses less number of bits to make storage smaller.

While the objects palettes handle are already represented by integer IDs, shrinking IDs in cases where only a few appear can further reduce storage space and network traffic volume.

    • index

      int index(T object)
      Returns the ID of an object in this palette.

      Parameters:
      object - the object to look up
      Returns:
      the ID of an object in this palette
