Standard_EXPORT | IGESDefs_UnitsData ()
Standard_EXPORT void | Init (const Handle(Interface_HArray1OfHAsciiString)&unitTypes, const Handle(Interface_HArray1OfHAsciiString)&unitValues, const Handle(TColStd_HArray1OfReal)&unitScales)
| This method is used to set the fields of the class UnitsData - unitTypes : Types of the units being defined - unitValues : Unit Values of the units - unitScales : Multiplicative Scale Factors raises exception if lengths of unitTypes, unitValues and unitScale are not same .
Standard_EXPORT Standard_Integer | NbUnits () const
| returns the Number of units defined by this entity
Standard_EXPORT Handle_TCollection_HAsciiString | UnitType (const Standard_Integer UnitNum) const
| returns the Type of the UnitNum'th unit being defined raises exception if UnitNum <= 0 or UnitNum > NbUnits()
Standard_EXPORT Handle_TCollection_HAsciiString | UnitValue (const Standard_Integer UnitNum) const
| returns the Units of the UnitNum'th unit being defined raises exception if UnitNum <= 0 or UnitNum > NbUnits()
Standard_EXPORT Standard_Real | ScaleFactor (const Standard_Integer UnitNum) const
| returns the multiplicative scale factor to be apllied to the UnitNum'th unit being defined raises exception if UnitNum <= 0 or UnitNum > NbUnits()
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const
