Member Typedef Documentation

Construct_line_2

typedef unspecified_type OptimalTransportationReconstructionTraits_2::Construct_line_2

A function object to construct a Line_2.

Must provides: Line_2 operator()(Point p, Vector v), which constructs a 2D line from a point and a vector.

Construct_point_2

typedef unspecified_type OptimalTransportationReconstructionTraits_2::Construct_point_2

A function object to construct a Point_2.

Must provides: Point_2 operator()(FT x, FT y), which constructs a 2D point from its coordinates.

Construct_vector_2

typedef unspecified_type OptimalTransportationReconstructionTraits_2::Construct_vector_2

A function object to construct a Vector_2.

Must provides: Vector_2 operator()(FT x, FT y), which constructs a 2D vector from its coordinates, and Vector_2 operator()(Point p0, Point p1), which constructs a 2D vector from 2 points.

FT

typedef unspecified_type OptimalTransportationReconstructionTraits_2::FT

A coordinate type.

The type must provide a copy constructor, assignment, comparison operators, negation, multiplication, division and allow the declaration and initialization with a small integer and double constant (cf. requirements for number types). An obvious choice would be coordinate type of the point class.
