class Line from IGESGeom inherits IGESEntity
---Purpose: defines IGESLine, Type <110> Form <0>
-- in package IGESGeom
-- A line is a bounded, connected portion of a parent straight
-- line which consists of more than one point. A line is
-- defined by its end points.
--
-- From IGES-5.3, two other Forms are admitted (same params) :
-- 0 remains for standard limited line (the default)
-- 1 for semi-infinite line (End is just a passing point)
-- 2 for full infinite Line (both Start and End are abitrary)
uses
Pnt from gp,
XYZ from gp
is
Create returns mutable Line;
-- Specific Methods pertaining to the class
Init (me : mutable; aStart : XYZ; anEnd : XYZ);
---Purpose : This method is used to set the fields of the class Line
-- - aStart : Start point of the line
-- - anEnd : End point of the line
Infinite (me) returns Integer;
---Purpose : Returns the Infinite status i.e. the Form Number : 0 1 2
SetInfinite (me : mutable; status : Integer);
---Purpose : Sets the Infinite status
-- Does nothing if <status> is not 0 1 or 2
StartPoint(me) returns Pnt;
---Purpose : returns the start point of the line
TransformedStartPoint(me) returns Pnt;
---Purpose : returns the start point of the line after applying Transf. Matrix
EndPoint(me) returns Pnt;
---Purpose : returns the end point of the line
TransformedEndPoint(me) returns Pnt;
---Purpose : returns the end point of the line after applying Transf. Matrix
fields
--
-- Class : IGESGeom_Line
--
-- Purpose : Declaration of variables specific to the definition
-- of the Class Line.
--
-- Reminder : A Line instance is defined by :
-- A starting and ending point
theStart : XYZ;
theEnd : XYZ;
end Line;
