Detailed Description

template<typename T>
struct swoc::DiscreteRange< T >::lexicographic_order

Functor for lexicographic ordering. If, for some reason, an interval needs to be put in a container that requires a strict weak ordering, the default operator < will not work. Instead, this functor should be used as the comparison functor. E.g.

typedef std::set<Interval<T>, Interval<T>::lexicographic_order> container;

Note

Lexicographic ordering is a standard tuple ordering where the order is determined by pairwise comparing the elements of both tuples. The first pair of elements that are not equal determine the ordering of the overall tuples.
