    • index

      public int index(int x, int y, int z)
      Description copied from interface: DataPalette
      Returns the packet section index of the given coordinates.
      Specified by:
      index in interface DataPalette
      Parameters:
      x - x
      y - y
      z - z
      Returns:
      packed section index of the given coordinates

    • idAt

      public int idAt(int sectionCoordinate)
      Description copied from interface: DataPalette
      Returns the value of the given chunk coordinate.
      Specified by:
      idAt in interface DataPalette
      Parameters:
      sectionCoordinate - section index within the section
      Returns:
      section state of the given index

    • setIdAt

      public void setIdAt(int sectionCoordinate, int id)
      Description copied from interface: DataPalette
      Set a value in the chunk section. This method does not update non-air blocks count.
      Specified by:
      setIdAt in interface DataPalette
      Parameters:
      sectionCoordinate - section index within the section
      id - id value

    • paletteIndexAt

      public int paletteIndexAt(int packedCoordinate)
      Description copied from interface: DataPalette
      Returns the palette index of the given section index.
      Specified by:
      paletteIndexAt in interface DataPalette
      Parameters:
      packedCoordinate - section index
      Returns:
      palette index of the given section index

    • setPaletteIndexAt

      public void setPaletteIndexAt(int sectionCoordinate, int index)
      Description copied from interface: DataPalette
      Sets the index of the given section coordinate.
      Specified by:
      setPaletteIndexAt in interface DataPalette
      Parameters:
      sectionCoordinate - section index
      index - palette index

    • setPaletteIndexes

      public void setPaletteIndexes(long[] data, int bitsPerValue, int valuesPerLong)
      Stores palette indexes from a compact long array, replacing all current values. The data is kept packed unless written to; reads extract bits the slow way, since almost all work will use replaceIds or will only have a few reads.

      Only valid for local palettes (bitsPerValue <= 8).

      Parameters:
      data - compact long array
      bitsPerValue - bits per value
      valuesPerLong - packked values per long

    • createPackedValues

      public long[] createPackedValues(int bitsPerValue, int entries, boolean rawIds)
      Description copied from interface: DataPalette
      Packs the section values into a compact long array as used by the protocol.
      Specified by:
      createPackedValues in interface DataPalette
      Parameters:
      bitsPerValue - bits used per value
      entries - number of values
      rawIds - whether to pack raw ids instead of palette indexes (direct palette)
      Returns:
      compact long array of the values

    • size

      public int size()
      Description copied from interface: DataPalette
      Returns the size of the palette.
      Specified by:
      size in interface DataPalette
      Returns:
      palette size

    • idByIndex

      public int idByIndex(int index)
      Description copied from interface: DataPalette
      Returns the id assigned to the given palette index.
      Specified by:
      idByIndex in interface DataPalette
      Parameters:
      index - palette index
      Returns:
      id assigned to the given palette index

    • setIdByIndex

      public void setIdByIndex(int index, int id)
      Description copied from interface: DataPalette
      Assigns an id assigned to the given palette index.
