CGAL 5.5.2  dD Triangulations

The concept TriangulationDataStructure::Vertex
describes the type used by a TriangulationDataStructure
to store the vertices.
It sets requirements of combinatorial nature only, as geometry is not concerned here. In particular, we only require that the vertex holds a handle to a full cell incident to it in the triangulation.
CGAL::Triangulation_ds_vertex<TriangulationDataStructure_>
CGAL::Triangulation_vertex<TriangulationTraits_, Data, TriangulationDSVertex_>
Types  
typedef unspecified_type  Full_cell_handle 
A handle to a cell, which must be the same as the nested type TriangulationDataStructure::Full_cell_handle .  
Operations  
void  set_full_cell (Full_cell_handle c) 
Set c as the vertex's incident full cell. More...  
Full_cell_handle  full_cell () const 
Returns a handle to a full cell incident to the vertex.  
Validity Check  
bool  is_valid (bool verbose=false) const 
This is a function for debugging purpose. More...  
Input/Output  
These operators can be used directly and are called by the I/O operator of class  
template<class TriangulationDataStructure >  
std::ostream &  operator<< (std::ostream &os, const Triangulation_ds_vertex< TriangulationDataStructure > &v) 
Writes (possibly) noncombinatorial information about vertex v to the stream os .  
template<class TriangulationDataStructure >  
std::istream &  operator>> (std::istream &is, Triangulation_ds_vertex< TriangulationDataStructure > &v) 
Reads from stream is the vertex information written by operator<< .  
bool TriangulationDataStructure::Vertex::is_valid  (  bool  verbose = false  )  const 
This is a function for debugging purpose.
Performs some validity checks on the vertex v
.
It must at least check that v
has an incident full cell, which in turn must contain v
as one of its vertices.
Returns true
if all the tests pass, false
if any test fails. See the documentation for the models of this concept to see the additionnal (if any) validity checks that they implement.
void TriangulationDataStructure::Vertex::set_full_cell  (  Full_cell_handle  c  ) 
Set c
as the vertex's incident full cell.
c
must not be the defaultconstructed Full_cell_handle
.
