Detailed Description

template<typename CharType, collator_base::level_type default_level = collator_base::identical>
struct booster::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,collator_base::secondary> > data;

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

Constructor & Destructor Documentation

template<typename CharType , collator_base::level_type default_level = collator_base::identical>
booster::locale::comparator< CharType, default_level >::comparator ( std::locale const &  l = std::locale(),
collator_base::level_type  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

Member Function Documentation

template<typename CharType , collator_base::level_type default_level = collator_base::identical>
bool booster::locale::comparator< CharType, default_level >::operator() ( std::basic_string< CharType > const &  left,
std::basic_string< CharType > const &  right 
) const
inline

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