Detailed Description

template<typename CharType, collate_level default_level = collate_level::identical>
struct boost::locale::comparator< CharType, default_level >

This class can be used in STL algorithms and containers for comparison of strings with a level other than primary.

For example:

std::map<std::string,std::string,comparator<char,collate_level::secondary> > data;

Would create a map the keys of which are sorted using secondary collation level

Constructor & Destructor Documentation

comparator()

template<typename CharType , collate_level default_level = collate_level::identical>

boost::locale::comparator< CharType, default_level >::comparator ( const std::locale &  l = std::locale(), collate_level  level = default_level  )

inline

Create a comparator class for locale l and with collation leval level

Note

throws std::bad_cast if l does not have collator facet installed
