class VectorWithMagnitude from Geom2d inherits Vector from Geom2d
--- Purpose :
-- Defines a vector with magnitude.
-- A vector with magnitude can have a zero length.

Vec2d from gp,
Geometry from Geom2d
raises ConstructionError from Standard
is
Create (V : Vec2d) returns mutable VectorWithMagnitude;
--- Purpose : Creates a persistent copy of V.
Create (X, Y : Real) returns mutable VectorWithMagnitude;
--- Purpose : Creates a vector with two cartesian coordinates.
Create (P1, P2 : Pnt2d) returns mutable VectorWithMagnitude;
--- Purpose :
-- Creates a vector from the point P1 to the point P2.
-- The magnitude of the vector is the distance between P1 and P2
SetCoord (me : mutable; X, Y : Real);
--- Purpose : Set <me> to X, Y coordinates.
SetVec2d (me : mutable; V : Vec2d);
-- Purpose : Set <me> to V.X(), V.Y() coordinates.
SetX (me : mutable; X : Real);
--- Purpose : Changes the X coordinate of <me>.
SetY (me : mutable; Y : Real);
--- Purpose : Changes the Y coordinate of <me>
Magnitude (me) returns Real;
--- Purpose : Returns the magnitude of <me>.
SquareMagnitude (me) returns Real;
--- Purpose : Returns the square magnitude of <me>.
Add (me : mutable; Other : Vector);
--- Purpose :
-- Adds the Vector Other to <me>.
---C++: alias operator +=
Added (me; Other : Vector) returns mutable VectorWithMagnitude
--- Purpose :
-- Adds the vector Other to <me>.
---C++: alias operator +
is static;
Crossed (me; Other : Vector) returns Real;
--- Purpose :
-- Computes the cross product between <me> and Other
-- <me> ^ Other. A new vector is returned.
---C++: alias operator ^
Divide (me : mutable; Scalar : Real);
--- Purpose : Divides <me> by a scalar.
---C++: alias operator /=
Divided (me; Scalar : Real) returns mutable VectorWithMagnitude
--- Purpose :
-- Divides <me> by a scalar. A new vector is returned.
---C++: alias operator /
is static;
Multiplied (me; Scalar : Real) returns mutable VectorWithMagnitude
--- Purpose :
-- Computes the product of the vector <me> by a scalar.
-- A new vector is returned.
--
-- -C++: alias operator *
-- Collision with same operator defined for the class Vector!
is static;
Multiply (me : mutable; Scalar : Real);
--- Purpose :
-- Computes the product of the vector <me> by a scalar.
---C++: alias operator *=
Normalize (me : mutable)
--- Purpose : Normalizes <me>.
raises ConstructionError;
--- Purpose :
-- Raised if the magnitude of the vector is lower or equal to
-- Resolution from package gp.
Normalized (me) returns mutable VectorWithMagnitude
--- Purpose : Returns a copy of <me> Normalized.
raises ConstructionError
--- Purpose :
-- Raised if the magnitude of the vector is lower or equal to
-- Resolution from package gp.
is static;
Subtract (me : mutable; Other : Vector);
--- Purpose : Subtracts the Vector Other to <me>.
---C++: alias operator -=
Subtracted (me; Other : Vector) returns mutable VectorWithMagnitude
--- Purpose :
-- Subtracts the vector Other to <me>. A new vector is returned.
---C++: alias operator -
is static;
Transform (me: mutable; T : Trsf2d);
---Purpose: Applies the transformation T to this vector.
Copy (me) returns mutable like me;
--- Purpose: Creates a new object which is a copy of this vector.
