Struct is_iequal

boost::algorithm::is_iequal — case insensitive version of is_equal


// In header: <boost/algorithm/string/compare.hpp>

struct is_iequal {
  // construct/copy/destruct
  is_iequal(const std::locale & = std::locale());

  // public member functions
  template<typename T1, typename T2> 
    bool operator()(const T1 &, const T2 &) const;


Case insensitive comparison predicate. Comparison is done using specified locales.

is_iequal public construct/copy/destruct

  1. is_iequal(const std::locale & Loc = std::locale());



    locales used for comparison

is_iequal public member functions

  1. template<typename T1, typename T2> 
      bool operator()(const T1 & Arg1, const T2 & Arg2) const;

    Compare two operands. Case is ignored.
