[Olena-patches] proto-1.0 42: A basic property heredity system

Index: ChangeLog from simon odou &lt;simon(a)lrde.epita.fr&gt; * oln/core/entry.hh: New. Just a basic and temporary property heredity system. * oln/core/abstract/images.hh: Likewise. * oln/core/abstract/image_with_data.hh: Likewiwe. * oln/core/abstract/image_identity.hh: Likewiwe. * oln/core/1d/image1d.hh: Likewiwe. * oln/core/2d/image2d.hh: Likewiwe. * oln/core/3d/image3d.hh: Likewiwe. * tests/core/tests/readonly_image: Likewiwe. * tests/core/tests/readwrite_image: Likewiwe. * oln/core/tags.hh: Remove. Old heredity system. * oln/makefile.src: Remove tags.hh, add entry.hh. oln/core/1d/image1d.hh | 8 - oln/core/2d/image2d.hh | 8 - oln/core/3d/image3d.hh | 8 - oln/core/abstract/image_identity.hh | 2 oln/core/abstract/image_with_data.hh | 2 oln/core/abstract/images.hh | 2 oln/core/entry.hh | 64 +++++++++++++++ oln/core/tags.hh | 144 ----------------------------------- oln/makefile.src | 2 tests/core/tests/readonly_image | 4 tests/core/tests/readwrite_image | 5 - 11 files changed, 85 insertions(+), 164 deletions(-) Index: tests/core/tests/readonly_image --- tests/core/tests/readonly_image (revision 41) +++ tests/core/tests/readonly_image (working copy) @@ -24,8 +24,8 @@ typedef mlc_encoding_type_(value_type) value_storage_type; typedef array2d<value_storage_type> value_container_type; - typedef tag::readonly constness_tag; - typedef tag::dimension2 dimension_tag; + typedef prop_of<abstract::readonly_image> image_constness; + typedef prop_of<abstract::image2d> image_dimension; typedef mlc::no_type delegated_type; }; Index: tests/core/tests/readwrite_image --- tests/core/tests/readwrite_image (revision 41) +++ tests/core/tests/readwrite_image (working copy) @@ -17,6 +17,9 @@ struct props <cat::image, dummy_image> : public default_props < cat::image > { + typedef prop_of<abstract::readwrite_image> image_constness; + typedef prop_of<abstract::image2d> image_dimension; + typedef size2d size_type; typedef point2d point_type; typedef ntg::int_u8 value_type; @@ -24,8 +27,6 @@ typedef mlc_encoding_type_(value_type) value_storage_type; typedef array2d<value_storage_type> value_container_type; - typedef tag::readwrite constness_tag; - typedef tag::dimension2 dimension_tag; typedef mlc::no_type delegated_type; }; Index: oln/makefile.src --- oln/makefile.src (revision 41) +++ oln/makefile.src (working copy) @@ -38,7 +38,7 @@ core/coord.hh \ core/macros.hh \ core/props.hh \ - core/tags.hh \ + core/entry.hh \ core/value_box.hh \ fancy/iota.hh \ fancy/print.hh \ Index: oln/core/entry.hh --- oln/core/entry.hh (revision 0) +++ oln/core/entry.hh (revision 0) @@ -0,0 +1,64 @@ +// Copyright (C) 2005 EPITA Research and Development Laboratory +// +// This file is part of the Olena Library.
