Member Typedef Documentation

template<class Exact> typedef iter_traits<exact_type>::point_type oln::fwd_iter2d< Exact >::point_type

The associate image's type of point. Warning: Prefer the macros oln_point_type(Pointable) and oln_point_type_(Pointable) (the same without the 'typename' keyword) Reimplemented from oln::abstract::iter< Exact >. Definition at line 77 of file fwd_iter2d.hh.
