BitSet

Object Hierarchy:

Description:

    var bits = new BitSet (64);
    bits.set (0);
    bits.set (3);
    bits.set (7);
    assert (bits.get (3));
    assert (!bits.get (4));
    assert (bits.cardinality () == 3);

Content:

Creation methods:

• public BitSet (int size = 64)
  Creates a BitSet with the specified initial capacity in bits. All bits are initially zero. The BitSet will grow as needed.

Methods:

• public bool @get (int index)
  Returns the value of the bit at the specified index.
• public void @set (int index)
  Sets the bit at the specified index to 1.
• public void and (BitSet other)
  Performs a bitwise AND with another BitSet, modifying this BitSet in place. Bits beyond the other's length are cleared.
• public int cardinality ()
  Returns the number of bits that are set to 1.
• public void clearAll ()
  Sets all bits to 0.
• public void clearBit (int index)
  Sets the bit at the specified index to 0.
• public void flip (int index)
  Flips the bit at the specified index (0 becomes 1, 1 becomes 0).
• public bool isEmpty ()
  Returns whether all bits are 0.
• public int length ()
  Returns the index of the highest set bit plus one. Returns 0 if no bits are set.
• public void or (BitSet other)
  Performs a bitwise OR with another BitSet, modifying this BitSet in place.
• public string toString ()
  Returns a string representation of the BitSet.
• public void xor (BitSet other)
  Performs a bitwise XOR with another BitSet, modifying this BitSet in place.
