Geom2d_Vector Class Reference

The abstract class Vector describes the common
behavior of vectors in 2D space.
The Geom2d package provides two concrete
classes of vectors: Geom2d_Direction (unit vector)
and Geom2d_VectorWithMagnitude.

#include <Geom2d_Vector.hxx>

Inheritance diagram for Geom2d_Vector:

Public Member Functions
void	Reverse ()
	Reverses the vector <me>.
Handle_Geom2d_Vector	Reversed () const
	Returns a copy of <me> reversed.
Standard_Real	Angle (const Handle< Geom2d_Vector > &Other) const
	Computes the angular value, in radians, between this vector and vector Other. The result is a value between -Pi and Pi. The orientation is from this vector to vector Other. Raises VectorWithNullMagnitude if one of the two vectors is a vector with null magnitude because the angular value is indefinite.
void	Coord (Standard_Real &X, Standard_Real &Y) const
	Returns the coordinates of <me>.
virtual Standard_Real	Magnitude () const =0
	Returns the Magnitude of <me>.
virtual Standard_Real	SquareMagnitude () const =0
	Returns the square magnitude of <me>.
Standard_Real	X () const
	Returns the X coordinate of <me>.
Standard_Real	Y () const
	Returns the Y coordinate of <me>.
virtual Standard_Real	Crossed (const Handle< Geom2d_Vector > &Other) const =0
	Cross product of <me> with the vector <Other>.
Standard_Real	Dot (const Handle< Geom2d_Vector > &Other) const
	Returns the scalar product of 2 Vectors.
gp_Vec2d	Vec2d () const
	Returns a non persistent copy of <me>.
