raises OutOfRange
is
Create returns mutable WitnessLine;
-- Specific Methods pertaining to the class
Init (me : mutable;
dataType : Integer;
aDisp : Real;

---Purpose : This method is used to set the fields of the class
-- WitnessLine
-- - dataType : Interpretation Flag, always = 1
-- - aDispl : Common z displacement
-- - dataPoints : Data points
Datatype (me) returns Integer;
---Purpose : returns Interpretation Flag, always = 1
NbPoints (me) returns Integer;
---Purpose : returns number of Data Points
ZDisplacement (me) returns Real;
---Purpose : returns common Z displacement
Point (me; Index : Integer) returns Pnt
raises OutOfRange;
---Purpose : returns Index'th. data point
-- raises exception if Index <= 0 or Index > NbPoints
TransformedPoint (me; Index : Integer) returns Pnt
raises OutOfRange;
---Purpose : returns data point after Transformation.
-- raises exception if Index <= 0 or Index > NbPoints
fields
--
-- Class : IGESDimen_WitnessLine

-- Purpose : Declaration of variables specific to the definition
-- of the Class WitnessLine.
--
-- Reminder : A WitnessLine instance is defined by :
-- - InterpretFlag : Interpretation Flag, always = 1
-- - ZDisplacement : Common z displacement
-- - DataPoints : Data points
-- A WitnessLine Entity contains one or more straight line segments
-- associated with drafting entities of various types. Each line segment
-- may be visible or invisible.
