typedef unspecified_type Alpha_status_iterator
 An iterator with value type CGAL::Alpha_status<NT>.
 

Creation

 AlphaShapeCell_3 ()
 default constructor.
 
 AlphaShapeCell_3 (const Vertex_handle &v0, const Vertex_handle &v1, const Vertex_handle &v2, const Vertex_handle &v3)
 constructor setting the incident vertices.

 constructor setting the incident vertices and the neighboring cells.
 

Access Functions

NT get_alpha ()
 Returns the alpha value of the cell.
 
Alpha_status_iterator get_facet_status (int i)
 Returns an iterator on the CGAL::Alpha_status<NT> of the facet i of the cell.
 

Modifiers

void set_alpha (const NT &alpha)
 Sets the critical value of the cell.
 
void set_facet_status (int i, Alpha_status_iterator as)
 Sets the iterator pointing to the CGAL::Alpha_status<NT> of the facet i of the cell.
 

Member Typedef Documentation

typedef unspecified_type AlphaShapeCell_3::NT

A number type.

Must be the same as the number type used in the traits class of the triangulation underlying the alpha shape.
