The dynamic_property_maps have no name

[maxGimeno]

Issue Details

The dynamic-property_maps, if used on a surface_mesh, will internally call the Surface_mesh::add_property() function. The problem is that a dynamic_property_map has no name parmeter to forward to the surface_mesh, which makes it impossible to retrieve the property once added.

I propose either :

• to add an overload to the dynamic get() functions that takes a std::string name as parameter, that would be forwarded to the surface_mesh
• or to add a std::string name to thedynamic_XXX_property_t structs and the constructor to initialize it, so we can keep the boost get() API and still have a name to give to the surface_mesh.

That would help to BGLize the read_off() functions, within the scope of the reorganization of the CGAL IO functions.

@CGAL/geometryfactory what do you think ?

What's the issue? it has an auto removal feature so why would you like to retrieve it? You are not supposed to lose the reference over it.

[maxGimeno]

What is the point of using the surface_mesh mechanism as an internal mechanism then ?

[sloriot]

You are supposed to keep the reference over the map otherwise it will be deleted.

Seems like this feature request is invalid ? @maxGimeno @sloriot

Again I'm not sure to understand the question, but if I understand it correctly then it should be closed :)

Max Lyon told me that in OpenMesh they introduce with 8.1 a PropertyManager, and properties without name that get deleteted when the property handle goes out of scope. It is maybe easier to discuss this the next time @sloriot is at GF. See the doc of their daily build.

I don't need this anymore and don't remember why I said that. Probably I didn't understand how to use the dyamic properties. I think this issue can be closed now.
