deferred class Vector from Geom2d inherits Geometry from Geom2d
--- Purpose : 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.
uses Ax2d from gp,
Pnt2d from gp,
Vec2d from gp
raises DomainError from Standard,
VectorWithNullMagnitude from gp
is
Reverse (me : mutable);
--- Purpose : Reverses the vector <me>.
Reversed (me) returns mutable like me
--- Purpose : Returns a copy of <me> reversed.
is static;
Angle (me; Other : Vector) returns Real
--- Purpose : 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.
raises VectorWithNullMagnitude;
Coord (me; X, Y : out Real);
--- Purpose : Returns the coordinates of <me>.
Magnitude (me) returns Real
--- Purpose : Returns the Magnitude of <me>.
is deferred;
SquareMagnitude (me) returns Real
--- Purpose : Returns the square magnitude of <me>.
is deferred;
X (me) returns Real;
--- Purpose : Returns the X coordinate of <me>.
Y (me) returns Real;
--- Purpose : Returns the Y coordinate of <me>.
Crossed (me; Other : Vector) returns Real
--- Purpose : Cross product of <me> with the vector <Other>.
is deferred;
Dot (me; Other : Vector) returns Real;
--- Purpose : Returns the scalar product of 2 Vectors.
Vec2d (me) returns Vec2d;
--- Purpose : Returns a non persistent copy of <me>.
