class BoundedSurface from IGESGeom inherits IGESEntity
---Purpose: defines BoundedSurface, Type <143> Form <0>
-- in package IGESGeom
-- A bounded surface is used to communicate trimmed
-- surfaces. The surface and trimming curves are assumed
-- to be represented parametrically.
uses
Boundary from IGESGeom,
HArray1OfBoundary from IGESGeom
raises OutOfRange
is
Create returns mutable BoundedSurface;
-- Specific Methods pertaining to the class
Init (me : mutable;
aType : Integer;
aSurface : IGESEntity;
allBounds : HArray1OfBoundary);
---Purpose : This method is used to set the fields of the class
-- BoundedSurface
-- - aType : Type of bounded surface representation
-- - aSurface : Surface entity to be bounded
-- - allBounds : Array of boundary entities
RepresentationType (me) returns Integer;
---Purpose : returns the type of Bounded surface representation
-- 0 = The boundary entities may only reference model space curves
-- 1 = The boundary entities may reference both model space curves
-- and associated parameter space curve representations
Surface (me) returns IGESEntity;
---Purpose : returns the bounded surface
NbBoundaries (me) returns Integer;
---Purpose : returns the number of boundaries
Boundary (me; Index : Integer) returns Boundary
raises OutOfRange;
---Purpose : returns boundary entity
-- raises exception if Index <= 0 or Index > NbBoundaries()
fields
--
-- Class : IGESGeom_BoundedSurface
--
-- Purpose : Declaration of variables specific to the definition
-- of the Class BoundedSurface.
--
-- Reminder : A BoundedSurface instance is defined by :
-- The type of bounded surface representation, the surface
-- entity bounded and a collection of boundary entities
theType : Integer;
theSurface : IGESEntity;
theBoundaries : HArray1OfBoundary;
end BoundedSurface;
