#include <boost/bit_logic/bit_container_type.hpp> 
   void flip ( ) ; 
   void flip ( size_type bit_idx ) ; 
   void flip ( size_type upper_bit_idx , size_type lower_bit_idx ) ;

Note: These functions are equivelant for all bit_container types. bit_array<N>, bit_vector, bit_container_adaptor

The flip() function inverts bit elements within a bit container. The no argument function flips every bit, the single argument version only flips the bit at a given index, and the multi-argument function flips the bits within the closed range of bit elements of a bit container.

For example:

 bit_vector<> v (9); // could also be a bit_array<9>
 cout << v << endl ;						  
 v.flip();
 cout << v << endl ;
 v.flip(7,1);
 cout << v << endl ;
 v.flip(6,2);
 cout << v << endl ;						  
 v.flip(5,3);
 cout << v << endl ;
 v.flip(4);
 cout << v << endl ;

This code would produce this output:

 000000000						  
 111111111
 100000001
 101111101
 101000101
 101010101

No argument flip throws no exceptions. Single argument flip can throw bit_out_of_bounds, and two argument flip can throw any of the following.

std::logic_error	Backwards ordering of range selction
bit_logic::bit_out_of_bounds	Index exceeds boundaries of container
