- #ifndef _STLP_BITSET
- // This implementation of bitset<> has a second template parameter,
- // _WordT, which defaults to unsigned long. *YOU SHOULD NOT USE
- // THIS FEATURE*. It is experimental, and it may be removed in
- // future releases.
- // A bitset of size N, using words of type _WordT, will have
- // N % (sizeof(_WordT) * CHAR_BIT) unused bits. (They are the high-
- // order bits in the highest word.) It is a class invariant
- // of class bitset<> that those unused bits are always zero.
- // Most of the actual code isn't contained in bitset<> itself, but in the
- // base class _Base_bitset. The base class works with whole words, not with
- // individual bits. This allows us to specialize _Base_bitset for the
- // important special case where the bitset is only a single word.
- // The C++ standard does not define the precise semantics of operator[].
- // In this implementation the const version of operator[] is equivalent
- // to test(), except that it does no range checking. The non-const version
- // returns a reference to a bit, again without doing any range checking.
