https://svn.lrde.epita.fr/svn/oln/trunk/olena Index: ChangeLog from Thierry Geraud &lt;thierry.geraud(a)lrde.epita.fr&gt; Add some 2d window types and refactor window impl hierarchy. * oln/core/2d/vline2d.hh, * oln/core/2d/hline2d.hh, * oln/core/2d/rectangle2d.hh, * oln/core/internal/window.hh: New. * oln/core/concept/window.hh (op_unary_minus_): New. * oln/core/gen/dpoints_piter.hh: Cosmetic change. * oln/core/gen/window.hh (window_): Rename as... (gen_window): ...this and inherit from internal::window_. (fwd_qiter, bkd_qiter, take, impl_op_unary_minus_): Move to... (internal::window_): ...here. * oln/core/2d/window2d.hh (window2d): Replace window_ by gen_window. * oln/core/internal/window_base.hh (point): New. * oln/morpho/closing.hh, * oln/morpho/opening.hh: Fix. * oln/morpho/erosion.hh (erosion_on_function_): New version on rectangle2d. core/2d/hline2d.hh | 94 ++++++++++++++++++++++++++++++++++ core/2d/rectangle2d.hh | 116 +++++++++++++++++++++++++++++++++++++++++++ core/2d/vline2d.hh | 101 +++++++++++++++++++++++++++++++++++++ core/2d/window2d.hh | 27 ++++------ core/concept/window.hh | 11 +++- core/gen/dpoints_piter.hh | 2 core/gen/window.hh | 55 +++++--------------- core/internal/window.hh | 116 +++++++++++++++++++++++++++++++++++++++++++ core/internal/window_base.hh | 7 +- morpho/closing.hh | 2 morpho/erosion.hh | 23 +++++++- morpho/opening.hh | 2 12 files changed, 492 insertions(+), 64 deletions(-) Index: oln/core/concept/window.hh --- oln/core/concept/window.hh (revision 927) +++ oln/core/concept/window.hh (working copy) @@ -47,6 +47,8 @@ stc_typename(fwd_qiter); stc_typename(bkd_qiter); + Exact op_unary_minus_() const; + protected: Window(); @@ -61,7 +63,14 @@ { } -# endif + template <typename Exact> + Exact + Window<Exact>::op_unary_minus_() const + { + return exact(this)->impl_op_unary_minus_(); + } + +# endif // !
