Definition

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.

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.
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.

Input/Output
These operators can be used directly and are called by the I/O operator of class TriangulationDataStructure.
template<class TriangulationDataStructure>
std::ostream &	operator<< (std::ostream &os, const Triangulation_ds_vertex< TriangulationDataStructure > &v)
	Writes (possibly) non-combinatorial 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<<.

Member Function Documentation

is_valid()

bool TriangulationDataStructure::Vertex::is_valid

(

bool

verbose = false

)

const

This is a function for debugging purpose.

Debugging Support

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 additional (if any) validity checks that they implement.

set_full_cell()

void TriangulationDataStructure::Vertex::set_full_cell

(

Full_cell_handle

c

)

Set c as the vertex's incident full cell.

Precondition

c must not be the default-constructed Full_cell_handle.
