Hi, Daniel,

    

     Thanks for your reply. I mean in the source. Because sometimes I need to save the handles of some faces. After that, the triangulation will be changed by inserting new points. So I care about whether the handle I saved is still valid. So I want to check the implement of the handle class in the source. Is there exist a member function or global function which can check the validity?

Best

Hi, everyone,

     I am looking for the definition of Vertex_handle and Face_handle which are used in Triangulation package of CGAL, but I get nothing from CGAL. Who can tell me where they are in CGAL?

You mean in the source, or in the documentation?

If the later, both are handles (a bit like iterators):
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Circulator/Chapter_main.html#Section_76.1

to either a vertex:
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/TDS_2_ref/Concept_TriangulationDataStructure_2--Vertex.html
or a face:
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/TDS_2_ref/Concept_TriangulationDataStructure_2--Face.html

So, e.g it would be "v.point()", but "vh->point()" for a vertex handle.

Best,

Daniel
