Syntax:
#include <boost/bit_logic/bit_vector.hpp> bit_handle at ( size_type num ) ; bool at ( size_type num ) const ; The at() does a checked range lookup. It is intended to be safer than operator[], since it will throw an exception. In this class however, all accesses are checked and therefore this is just redundant for Container like interfaces. For example: bit_vector<> v ( 3 ) ; cout << v.at(5) ; Exceptions:
