flip

Flips the bit at the specified index (0 becomes 1, 1 becomes 0).

If the index is beyond the current capacity, the BitSet is grown and the bit is set to 1.

Example:

    var bits = new BitSet (8);
    bits.flip (3);
    assert (bits.get (3));
    bits.flip (3);
    assert (!bits.get (3));

Parameters:

index

the zero-based bit index. Must be >= 0.
