  • Method Details

    • set

      public void set(int position)

    • clear

      public void clear(int position)

    • setInclusion

      public boolean setInclusion(FixedBitSet bitset)
      Parameters:
      bitset -
      Returns:
      true if bitset contains this set (this <= bitset)

    • union

      public void union(FixedBitSet b)

    • intersect

      public void intersect(FixedBitSet b)

    • setMinus

      public void setMinus(FixedBitSet b)

    • intersectCardinality

      public int intersectCardinality(FixedBitSet b)

    • complement

    • complement

      public void complement()

    • nextOnBit

      public int nextOnBit(int fromIndex)

      Parameters:
      fromIndex -
      Returns:
      Next set member whose index is >= fromIndex. -1 if none.
