- Use `value_type` when the returned type is not a reference
- Enforce `reference = value_type` if the returned type is not
a reference (to avoid `typename PM::reference r = get(m, k)`,
which will take a ref to a temporary if the `reference`
typedef is an actualy reference)
- Do not use `put_get_helper` if the property map is not a `lvalue`
**mutable** property map: the `put()` is `map[k] = v`, which
is broken if `operator[]` does not return a reference
- The concept `boost::lvalue_property_map_tag` requires `operator[](key)`,
not a reference in `get(map, key)`. You can have a readable property map
returning a reference through its `get(map, key)`, but if there is
no `operator[]`, it's just a `boost::readable_property_map_tag`
- Some const correctness to avoid copying maps with state
or heavy keys in `get(map, key)` / `put(map, key, value)`
- Base the category of a wrapping pmap on what it offers instead
of just forwarding the base property map's category
- Tried to do something like mutable lvalue pmap:
* `value_type& operator[](key&)`
* `ref get(map, const key&)`
* `put(map, const key&, const value_type&)`
and non-mutable lvalue pmap:
* `const value_type& operator[](const key&)`
* `ref get(map, const key&)`
but not everything fits properly...
right after the merge of 4.14 release branch
+ manual fix on one line in:
* Arrangement_on_surface_2/include/CGAL/IO/Arr_text_formatter.h
* .travis/generate_travis.sh
TriangulationCellBase_3 does not request a circumcenter;
DelaunayTriangulationCellBase_3 does.
Delaunay_triangulation_3 only compiled because
Triangulation_cell_base_3 (and Triangulation_ds_cell_base_3 !)
provided circumcenter() operators and DT3 inherited T3's TDS.
- The circumcenter() functions are removed where they shouldn't exist
- DT3 uses DT_cell_base_3 as cell base instead of T_cell_base_3
- Concepts/Classes that supposedly only required TriangulationCellBase_3
and then built Delaunay triangulations with that (Alpha Shapes, etc.)
are upgraded to request DelaunayTriangulationCellBase_3 (anyway, it
wouldn't compile if you actually provided a model of
TriangulationCellBase_3)
- Fixed various wrong templates in classes/concepts such as
MeshVertexBase_3 not refining RegularTriangulationVertexBase_3
and (only in the doc) defaulting to Triangulation_vertex_base_3
- Removed the deprecated class (for 4+ years) T_cell_base_with_circumcenter
Now that we require CMake>=3.1, we can forget a lot of old CMake policies.
`CMP0053` `OLD` behavior is still needed, because of a bug in Qt5 CMake files, but it will
not be set with CMake>=3.10. Let's assume that a recent CMake version means
a recent Qt5 version.
