Detailed Description

template<typename ValueT, typename FunT = less>
class boost::attribute_value_ordering< ValueT, FunT >

Ordering predicate, based on attribute values associated with records.

This predicate allows to order log records based on values of a specifically named attribute associated with them. Two given log records being compared should both have the specified attribute value of the specified type to be able to be ordered properly. As a special case, if neither of the records have the value, these records are considered equivalent. Otherwise, the ordering results are unspecified.
