| #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. |
