CGAL users discussion list

I know these functions,and I ues function *.get_alpha_shape_facets() to find some kinds of faces,and store them in std:list(Facet).But I do not know the class Facet,so you can tell me how to output coordinates of vertices of facets by iterior of std:list??

look at the page http://www.cgal.org/Manual/3.3/doc_html/cgal_manual/Alpha_shapes_3_ref/Class_Alpha_shape_3.html
of the doc :
yu have the classify member fuctions to know the status of a face
and the get_alpha_shape_xxxx functions to retrieve the alpa-shape faces
by types ans status

       now I use the algorithm of 3D alpha-shape,and want to output some information about     regular,interior,exterior,singular faces,but cgal does not provide the class explicitly,could you show me a example? how to do this? if you did not know ,could you tell me who can help me?
