https://svn.lrde.epita.fr/svn/oln/trunk/olena Index: ChangeLog from Roland Levillain &lt;roland(a)lrde.epita.fr&gt; Fix the identity and neighborhood addition morphers. * oln/automatic/image_having_neighborhood.hh: Add a forward declaration of oln::abstract::image_having_neighborhood. (impl<abstract::image_having_neighborhood, morpher::tag::identity, E>): Inherit from abstract::image<E>. (impl_neighborhood): Make it const. Get the exact type before calling delegate(). * oln/core/abstract/image_having_neighborhood.hh (oln/automatic/image_having_neighborhood.hh): Include it. (oln::abstract::image_having_neighborhood::neighborhood): New. (case_<image_hierarchy_wrt_neighborhood, E, 1>): Only inherit from oln::abstract::image_having_neighborhood if neighborhood is different from mlc::not_found. (oln::ext_vtype<image_entry<E>, typedef_::neighborhood_type>): Remove. * oln/core/image_entry.hh (single_vtype<image_entry<E>, typedef_::morpher_type>): Remove. Instead, defined the `morpher' virtual type... (vtypes< image_entry<E> >): ...here. * oln/morpher/internal/image_extension.hh (image_extension): Fix the inheritance: derive from `oln::image_entry<Exact>' instead of `oln::image_entry< image_extension<Image, Exact> >'. * oln/morpher/identity.hh (oln/morpher/tags.hh): Include it. (oln::single_vtype<morpher::identity<Image>, typedef_::morpher_type>): Remove. Instead, defined the `morpher' virtual type... (oln::vtypes< morpher::identity<Image> >): ...here (oln::morpher::tag::identity): Move... * oln/morpher/tags.hh: ...here (new file). * oln/morpher/add_neighborhood.hh (oln/morpher/tags.hh) (oln/core/2d/aliases.hh): Include them. (oln::single_vtype<morpher::add_neighborhood<Image>, typedef_::morpher_type>): Remove. Instead, defined the `morpher' virtual type... (oln::vtypes< morpher::add_neighborhood<Image> >): ...here (oln::morpher::add_neighborhood::neighborhood_t): Fix the virtual type retrieval: get it from `self_t', not from `Image'. (ext_vtype<morpher::add_neighborhood< oln::image2d<T> >, typedef_::neighborhood_type>): Remove. Remove corresponding forward declarations as well. (oln::morpher::tag::add_neighborhood): Move... * oln/morpher/tags.hh: ...here. * tests/identity_morpher.cc, tests/morphers.cc: Fix the test. Add more static assertions. * oln/Makefile.am (nobase_oln_HEADERS): Add core/2d/neighb2d.hh, core/abstract/neighborhood.hh, core/gen/neighb.hh and core/neighborhood_entry.hh. * oln/core/2d/image2d.hh: Fix copyright header. oln/Makefile.am | 4 + oln/automatic/image_having_neighborhood.hh | 28 +++++++---- oln/core/2d/image2d.hh | 3 - oln/core/abstract/image_having_neighborhood.hh | 33 +++++-------- oln/core/image_entry.hh | 14 +---- oln/morpher/add_neighborhood.hh | 57 +++++----------------- oln/morpher/identity.hh | 16 +----- oln/morpher/internal/image_extension.hh | 9 +-- oln/morpher/tags.hh | 49 +++++++++++++++++++ tests/identity_morpher.cc | 20 +++++++ tests/morphers.cc | 63 ++++++++++++++++++------- 11 files changed, 180 insertions(+), 116 deletions(-) Index: tests/morphers.cc --- tests/morphers.cc (revision 554) +++ tests/morphers.cc (working copy) @@ -25,38 +25,67 @@ // reasons why the executable file might be covered by the GNU General // Public License. -/// Test the identity morpher. +/// Test some morphers. + +#include <mlc/assert.hh> +#include <mlc/is_a.hh> // FIXME: We should not include oln/basics2d.hh, but oln/core/2d/image2d.hh. #include <oln/basics2d.hh> #include <oln/morpher/identity.hh> #include <oln/morpher/add_neighborhood.hh> -// FIXME: Fake! -// To be removed as soon as neighborhood2d is written. -namespace oln -{ - struct neighborhood2d {}; -} int main() { - typedef oln::image2d<int> image_t; + /*----------------. + | image2d<char>. | + `----------------*/ + + typedef oln::image2d<char> image_t; + // Sanity check: abstractions realized by oln::image2d. + mlc::assert_< mlc_is_a_(image_t, oln::abstract::image2d) >::check(); + mlc::assert_< mlc_is_a_(image_t, + oln::abstract::grey_level_image) >::check(); + mlc::assert_< mlc_is_a_(image_t, + oln::abstract::not_binary_image) >::check(); image_t ima (42, 51); + + /*------------------------------------. + | add_neighborhood< image2d<char> >. | + `------------------------------------*/ + typedef oln::morpher::add_neighborhood<image_t> image_with_nbh_t; - // FIXME: Using `oln_type_of_(image_t, neighborhood)' seems - // mandatory here.
