Definition

The concept TriangulationVertex describes the requirements on the type used by the class CGAL::Triangulation<TriangulationTraits_, TriangulationDataStructure_>, and its derived classes, to represent a vertex.

Refines:: TriangulationDSVertex We only list below the additional specific requirements of TriangulationVertex. Compared to TriangulationDSVertex, the main difference is the addition of an association of the vertex with a geometric point.

Input/Output

These operators can be used directly and are called by the I/O operator of class Triangulation.

Member Typedef Documentation

◆ Point

typedef unspecified_type TriangulationVertex::Point

The type of the point stored in the vertex.

It must be the same as the point type TriangulationTraits::Point_d when the TriangulationVertex is used in the class Triangulation<TriangulationTraits, TriangulationDataStructure_>.

Constructor & Destructor Documentation

◆ TriangulationVertex() [1/3]

TriangulationVertex::TriangulationVertex	(	Full_cell_handle	c,
		const Point &	p
	)

Constructs a vertex with incident full cell c.

The vertex is embedded at point p.

◆ TriangulationVertex() [2/3]

TriangulationVertex::TriangulationVertex ( const Point & p )

Same as above, but without incident full cell.

◆ TriangulationVertex() [3/3]

TriangulationVertex::TriangulationVertex ( )

Same as above, but with a default-constructed Point.

Member Function Documentation

◆ operator<<()

std::ostream& TriangulationVertex::operator<<	(	std::ostream &	os,
		const TriangulationVertex &	v
	)

Outputs the non-combinatorial information given by the vertex, i.e., the point and other possible information.

◆ operator>>()

std::istream& TriangulationVertex::operator>>	(	std::istream &	is,
		TriangulationVertex &	v
	)

Inputs the non-combinatorial information given by the vertex, i.e., the point and other possible information.

◆ point()

const Point& TriangulationVertex::point ( ) const

Returns the vertex's position.

◆ set_point()

void TriangulationVertex::set_point ( const Point & p )

The parameter p becomes the new geometrical position of the vertex.
