class Boundary from IGESGeom inherits IGESEntity
---Purpose: defines IGESBoundary, Type <141> Form <0>
-- in package IGESGeom
-- A boundary entity identifies a surface boundary consisting
-- of a set of curves lying on the surface
uses
HArray1OfInteger from TColStd,
HArray1OfIGESEntity from IGESData,
HArray1OfHArray1OfIGESEntity from IGESBasic
raises DimensionMismatch, OutOfRange
is
Create returns mutable Boundary;
-- Specific Methods pertaining to the class
Init (me : mutable;
aType : Integer;
aPreference : Integer;
aSurface : IGESEntity;
allModelCurves : HArray1OfIGESEntity;
allSenses : HArray1OfInteger;
allParameterCurves : HArray1OfHArray1OfIGESEntity)
raises DimensionMismatch;
---Purpose : This method is used to set the fields of the class
-- Boundary
-- - aType : Type of bounded surface representation
-- - aPreference : Preferred representation of
-- Trimming Curve
-- - aSurface : Untrimmed surface to be bounded
-- - allModelCurves : Model Space Curves
-- - allSenses : Orientation flags of all Model Space
-- Curves
-- - allParameterCurves : Parameter Space Curves
-- raises exception if allSenses, allModelCurves and
-- allParameterCurves do not have same dimensions
BoundaryType (me) returns Integer;
---Purpose : returns type of bounded surface representation
-- 0 = Boundary entities may only reference model space trimming
-- curves. Associated surface representation may be parametric
-- 1 = Boundary entities must reference model space curves and
-- associated parameter space curve collections. Associated
-- surface must be a parametric representation
PreferenceType (me) returns Integer;
---Purpose : returns preferred representation of trimming curves
-- 0 = Unspecified
-- 1 = Model space
-- 2 = Parameter space
-- 3 = Representations are of equal preference
Surface (me) returns IGESEntity;
---Purpose : returns the surface to be bounded
NbModelSpaceCurves (me) returns Integer;
---Purpose : returns the number of model space curves
ModelSpaceCurve (me; Index : Integer) returns IGESEntity
raises OutOfRange;
---Purpose : returns Model Space Curve
-- raises exception if Index <= 0 or Index > NbModelSpaceCurves()
Sense(me; Index: Integer) returns Integer
raises OutOfRange;
---Purpose : returns the sense of a particular model space curve
-- 1 = model curve direction does not need reversal
-- 2 = model curve direction needs to be reversed
-- raises exception if Index <= 0 or Index > NbModelSpaceCurves()
NbParameterCurves (me; Index : Integer) returns Integer
raises OutOfRange;
---Purpose : returns the number of parameter curves associated with one
-- model space curve referred to by Index
-- raises exception if Index <= 0 or Index > NbModelSpaceCurves()
ParameterCurves (me; Index : Integer) returns HArray1OfIGESEntity
raises OutOfRange;
---Purpose : returns an array of parameter space curves associated with
-- a model space curve referred to by the Index
-- raises exception if Index <= 0 or Index > NbModelSpaceCurves()
ParameterCurve (me; Index, Num: Integer) returns mutable IGESEntity
raises OutOfRange;
---Purpose : returns an individual parameter curve
-- raises exception if Index or Num is out of range
fields
--
-- Class : IGESGeom_Boundary
--
-- Purpose : Declaration of variables specific to the definition
-- of the Class Boundary.
--
-- Reminder : A Boundary instance is defined by :
-- A surface boundary consisting of a set of curves lying
-- on the surface
theType : Integer;
thePreference : Integer;
theSurface : IGESEntity;
theModelCurves : HArray1OfIGESEntity;
theSenses : HArray1OfInteger;
theParameterCurves : HArray1OfHArray1OfIGESEntity;
end Boundary;
