Detailed Description

template<size_t _Nb>
class benzene_bitset< _Nb >

The bitset class represents a fixed-size sequence of bits.

(Note that bitset does not meet the formal requirements of a container. Mainly, it lacks iterators.)

The template argument, Nb, may be any non-negative number, specifying the number of bits (e.g., "0", "12", "1024*1024").

In the general unoptimized case, storage is allocated in word-sized blocks. Let B be the number of bits in a word, then (Nb+(B-1))/B words will be used for storage. B - NbB bits are unused. (They are the high-order bits in the highest word.) It is a class invariant that those unused bits are always zero.

If you think of bitset as "a simple array of bits," be aware that your mental picture is reversed: a bitset behaves the same way as bits in integers do, with the bit at index 0 in the "least significant / right-hand" position, and the bit at index Nb-1 in the "most significant / left-hand" position. Thus, unlike other containers, a bitset's index "counts from right to left," to put it very loosely.

This behavior is preserved when translating to and from strings. For example, the first line of the following program probably prints "b('a') is 0001100001" on a modern ASCII system.

     #include <bitset>
     #include <iostream>
     #include <sstream>

     using namespace std;

     int main()
     {
         long         a = 'a';
         bitset<10>   b(a);

         cout << "b('a') is " << b << endl;

         ostringstream s;
         s << b;
         string  str = s.str();
         cout << "index 3 in the string is " << str[3] << " but\n"
              << "index 3 in the bitset is " << b[3] << endl;
     }

Also see http://gcc.gnu.org/onlinedocs/libstdc++/ext/sgiexts.html#ch23 for a description of extensions.

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.

Extra confusion can result due to the fact that the storage for _Base_bitset is a regular array, and is indexed as such. This is carefully encapsulated.

template<size_t _Nb>

benzene_bitset<_Nb> benzene_bitset< _Nb >::operator~ ( ) const [inline]

See the no-argument flip().

Definition at line 979 of file BenzeneBitset.hpp.

template<size_t _Nb>

benzene_bitset<_Nb>& benzene_bitset< _Nb >::reset ( size_t __position ) [inline]

Sets a given bit to false.

Parameters:

__position

The index of the bit.

Exceptions:

std::out_of_range

If pos is bigger the size of the set.

Same as writing set(pos,false).

template<size_t _Nb>

benzene_bitset<_Nb>& benzene_bitset< _Nb >::set	(	size_t	__position,
		bool	__val = `true`
	)			`[inline]`

Sets a given bit to a particular value.

Parameters:

	__position	The index of the bit.
	__val	Either true or false, defaults to true.

Exceptions:

std::out_of_range

If pos is bigger the size of the set.

template<size_t _Nb>

bool benzene_bitset< _Nb >::test ( size_t __position ) const [inline]

Tests the value of a bit.

Parameters:

__position

The index of a bit.

Returns:: The value at pos.

std::basic_string<_CharT, _Traits, _Alloc> benzene_bitset< _Nb >::to_string ( ) const [inline]

Returns a character interpretation of the bitset.

Returns:: The string equivalent of the bits.

Note the ordering of the bits: decreasing character positions correspond to increasing bit positions (see the main class notes for an example).
