bool none() const | Returns true if no bits are set. |
bool test(size_t n) const | Returns true if bit n is set. Throws out_of_range if n >= N. |
reference operator[](size_t n) | Returns a reference to bit n. Note that reference is a proxy class with an assignment operator and a conversion to bool, which allows you to use operator[] for assignment. That is, you can write both x = b[n] and b[n] = x. |
bool operator[](size_t n) const | Returns true if bit n is set. |
unsigned long to_ulong() const | Returns an unsigned long corresponding to the bits in *this. Throws overflow_error if it is impossible to represent *this as an unsigned long. (That is, if N is larger than the number of bits in an unsigned long and if any of the high-order bits are set. |
template<class Char, class Traits, class Alloc> basic_string <Char,Traits,Alloc> to_string() const | Returns a string representation of *this: each character is 1 if the corresponding bit is set, and 0 if it is not. In general, character position i corresponds to bit position N – 1 – i. Note that this member function relies on two language features, member templates and explicit function template argument specification, that are not yet universally available; this member function is disabled for compilers that do not support those features. Note also that the syntax for calling this member function is somewhat cumbersome. To convert a bitset b to an ordinary string, you must write b.template to_string<char, char_traits<char>, allocator<char> >() |
bitset operator&(const bitset&, const bitset&) | Bitwise and of two bitsets. This is a global function, not a member function. Note that the expression b1 & b2 is equivalent to creating a temporary copy of b1, using operator&=, and returning the temporary copy. |
bitset operator|(const bitset&, const bitset&) | Bitwise or of two bitsets. This is a global function, not a member function. Note that the expression b1 | b2 is equivalent to creating a temporary copy of b1, using operator|=, and returning the temporary copy. |
bitset operator^(const bitset&, const bitset&) | Bitwise exclusive or of two bitsets. This is a global function, not a member function. Note that the expression b1 ^ b2 is equivalent to creating a temporary copy of b1, using operator^=, and returning the temporary copy. |
template<class Char, class Traits, size_t N> basic_istream<Char, Traits>& operator>>(basic_istream<Char,Traits>& is, bitset<N>& x) | Extract a bitset from an input stream. This function first skips whitespace, then extracts up to N characters from the input stream. It stops either when it has successfully extracted N character, or when extraction fails, or when it sees a character that is something other than 1 (in which case it does not extract that character). It then assigns a value to the bitset in the same way as if it were initializing the bitset from a string. So, for example, if the input stream contains the characters '1100abc', it will assign the value 12ul to the bitset, and the next character read from the input stream will be a. |
template<class Char, class Traits, size_t N> basic_ostream<Char,Traits>& operator>>(basic_ostream<Char,Traits>& os, const bitset<N>& x) | Output a bitset to an output stream. This function behaves as if it converts the bitset to a string and then writes that string to the output stream. That is, it is equivalent to os << x.template to_string<Char,Traits,allocator<Char> >() |
