Iterates over the classes the instance is instantiated from.
Syntax
public const string enginedll = @"engine.dll";
[DllImport(enginedll, EntryPoint = "GetInstanceClassByIterator")]
public static extern Int64 GetInstanceClassByIterator(Int64 owlInstance, Int64 owlClass);
Property owlInstance
Size: 64 bit / 8 byte (value)
The handle to the specific instance in the design tree. The instance handle is static within one open model but is most probably different when the same instance is opened in another model. The instance is always exactly of one unique class.
Property owlClass
Size: 64 bit / 8 byte (value)
This attribute represents a handle to the class. The term owl is comming from W3C, the classes follow the expression power of Semantic Web concepts, therefore classes support multiple inheritance. Technically classes can also be distributed over different resources, however for this the parametric library is required as an extension on the basic Geometry Kernel API.
