https://svn.lrde.epita.fr/svn/oln/branches/cleanup-2008/milena Index: ChangeLog from Thierry Geraud &lt;thierry.geraud(a)lrde.epita.fr&gt; Make w_window tests pass with from_to instead of to_w_window. * mln/core/w_window.hh (win): Update sig. (clear): New. (from_to): New overload. * mln/core/internal/site_relative_iterator_base.hh: Update. * mln/core/neighb.hh: Update. * mln/core/concept/proxy.hh (from_to): New overload. * mln/core/concept/weighted_window.hh (sym): Update. * mln/core/concept/gpoint.hh (from_to): New overload. * mln/convert/to.hh: Decouple from convert::from_to so... (include from_to.hh): Replace by... (include from_to.hxx): ...this. Update includes. * mln/convert/to_image.hh: Fix temporary; O can be *-able. * mln/geom/bbox.hh: Likewise. * mln/convert/to_w_window.hh: Remove; obsolete because replaced by from_to. * mln/convert/from_to.hh: Fix ambiguities in multiple guards; keep only one. * mln/convert/all.hh, * tests/core/alias/w_window1d_int.cc, * tests/core/alias/w_window2d_int.cc, * tests/core/alias/w_window3d_int.cc: Update. * mln/convert/from_to.hxx: New. mln/convert/all.hh | 1 mln/convert/from_to.hh | 32 ---- mln/convert/from_to.hxx | 151 +++++++++++++++++++++++ mln/convert/to.hh | 7 - mln/convert/to_image.hh | 3 mln/core/concept/gpoint.hh | 34 +++++ mln/core/concept/proxy.hh | 30 ++++ mln/core/concept/weighted_window.hh | 4 mln/core/internal/site_relative_iterator_base.hh | 2 mln/core/neighb.hh | 1 mln/core/w_window.hh | 64 ++++++++- mln/geom/bbox.hh | 3 tests/core/alias/w_window1d_int.cc | 8 - tests/core/alias/w_window2d_int.cc | 8 - tests/core/alias/w_window3d_int.cc | 5 15 files changed, 302 insertions(+), 51 deletions(-) Index: tests/core/alias/w_window1d_int.cc --- tests/core/alias/w_window1d_int.cc (revision 2388) +++ tests/core/alias/w_window1d_int.cc (working copy) @@ -30,11 +30,12 @@ #include <mln/core/alias/w_window1d_int.hh> #include <mln/win/segment1d.hh> +#include <mln/convert/to.hh> +#include <mln/convert/to.hh> +#include <mln/convert/to_fun.hh> #include <mln/convert/to_image.hh> -#include <mln/convert/to_w_window.hh> -#include <mln/convert/to_fun.hh> #include <mln/estim/sum.hh> @@ -53,7 +54,8 @@ w_window1d_int w_win = make::w_window1d(ws); image1d<int> ima = convert::to_image(w_win); - w_window1d_int w_win_2 = mln::convert::to<w_window1d_int>(ima); + + w_window1d_int w_win_2 = convert::to<w_window1d_int>(ima); mln_assertion(w_win_2 == w_win); } Index: tests/core/alias/w_window2d_int.cc --- tests/core/alias/w_window2d_int.cc (revision 2388) +++ tests/core/alias/w_window2d_int.cc (working copy) @@ -1,4 +1,4 @@ -// Copyright (C) 2007 EPITA Research and Development Laboratory +// Copyright (C) 2007, 2008 EPITA Research and Development Laboratory // // This file is part of the Olena Library.
