      The number of bits set to true in this bitmap

    • isEmpty

      public boolean isEmpty()
      Specified by:
      isEmpty in interface ImmutableBitmap
      Returns:

    • 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

    • 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:
      union in interface ImmutableBitmap
      Parameters:
      otherBitmap - other bitmap
