  • Method Details

    • iterator

      public org.roaringbitmap.IntIterator iterator()
      Specified by:
      iterator in interface ImmutableBitmap
      Returns:
      an iterator over the set bits of this bitmap

    • get

      public boolean get(int value)
      Description copied from interface: ImmutableBitmap
      Returns true if the bit at position value is set
      Specified by:
      get in interface ImmutableBitmap
      Parameters:
      value - the position to check
      Returns:
      true if bit is set

    • size

      public int size()
      Specified by:
      size in interface ImmutableBitmap
      Returns:
      The number of bits set to true in this bitmap

    • toBytes

      public byte[] toBytes()
      Specified by:
      toBytes in interface ImmutableBitmap

    • isEmpty

      public boolean isEmpty()
      Specified by:
      isEmpty in interface ImmutableBitmap
      Returns:
      True if this bitmap is empty (contains no set bit)

    • union

      public ImmutableBitmap union(ImmutableBitmap otherBitmap)
      Description copied from interface: ImmutableBitmap
      Compute the bitwise-or of this bitmap with another bitmap. A new bitmap is generated. Note that the other bitmap should be of the same class instance.
      Specified by:
      union in interface ImmutableBitmap
      Parameters:
      otherBitmap - other bitmap

    • intersection

      public ImmutableBitmap intersection(ImmutableBitmap otherBitmap)
      Description copied from interface: ImmutableBitmap
      Compute the bitwise-and of this bitmap with another bitmap. A new bitmap is generated. Note that the other bitmap should be of the same class instance.
      Specified by:
      intersection in interface ImmutableBitmap
      Parameters:
      otherBitmap - other bitmap
