Detailed Description

template<class PointType_, class TLabel, class Storage>
template<bool Oriented>
class pgl::MonotoneChain< PointType_, TLabel, Storage >::BoundaryIterator< Oriented >

Forward iterator over the (optionally oriented) chain edges.

Edge i joins vertex i to vertex i + 1, so a chain with size() vertices has size() - 1 edges (and none when degenerate).
