class Vars from XSControl inherits TShared from MMgt
---Purpose : Defines a receptacle for externally defined variables, each
-- one has a name
--
-- I.E. a WorkSession for XSTEP is generally used inside a
-- context, which brings variables, especially shapes and
-- geometries. For instance DRAW or an application engine
--
-- This class provides a common form for this. It also provides
-- a default implementation (locally recorded variables in a
-- dictionary), but which is aimed to be redefined
uses CString, Transient, DictionaryOfTransient,
Pnt from gp, Pnt2d from gp,
Geometry from Geom, Curve from Geom, Curve from Geom2d, Surface from Geom,
Shape from TopoDS
is
Create returns mutable Vars;
Set (me : mutable; name : CString; val : Transient) is virtual;
Get (me; name : in out CString) returns Transient is virtual;
GetGeom (me; name : in out CString) returns Geometry is virtual;
GetCurve2d (me; name : in out CString) returns Curve from Geom2d is virtual;
GetCurve (me; name : in out CString) returns Curve from Geom is virtual;
GetSurface (me; name : in out CString) returns Surface from Geom is virtual;
SetPoint (me : mutable; name : CString; val : Pnt from gp) is virtual;
SetPoint2d (me : mutable; name : CString; val : Pnt2d from gp) is virtual;
GetPoint (me; name : in out CString; pnt : out Pnt from gp) returns Boolean is virtual;
GetPoint2d (me; name : in out CString; pnt : out Pnt2d from gp) returns Boolean is virtual;
SetShape (me : mutable; name : CString; val : Shape from TopoDS) is virtual;
GetShape (me; name : in out CString) returns Shape from TopoDS is virtual;
