	Compare two strings – equivalent to return left < right according to collation rules.

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 identical.

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

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 level level

Exceptions

std::bad_cast l does not have collator facet installed
