GetClassByNameW

Returns a handle to the class as stored inside.
When the class does not exist yet and the name is unique the class will be created on the fly and the handle will be returned.
When the name is not unique and given to an instance, objectTypeProperty or dataTypeProperty 0 will be returned.

//   Visual Studio for Windows
public:
__int64 __declspec(dllexport) __stdcall GetClassByNameW(
            __int64             model,
            const wchar_t       * name
        );

//   Linux, OS-X and non-Visual Studio Windows solutions
public:
int64_t GetClassByNameW(
            int64_t             model,
            const wchar_t       * name
        );

Property model

Size: 64 bit / 8 byte (value)
The handle to the model. The model handle is static during its existance. Several models can be opened simultaniously within one session. Different models are always independent, threads are allowed to be running on different models simultaniously.

Property name

Size: 64 bit / 8 byte (reference)
This attribute represents the name of the class (given as wchar_t array / Unicode). The name is given by the host and the attribute is not changed.

Example

Here you can find code snippits that show how the API call GetClassByNameW can be used.

#include 

int64_t model = CreateModel();

if (model) {
    //
    //  Classes
    //
    int64_t classArc3D = GetClassByNameW(model, L"Arc3D");

    //
    //  Datatype Properties (attributes)
    //
    int64_t propertyRadius = GetPropertyByNameW(model, L"radius"),
            propertyStart = GetPropertyByNameW(model, L"start"),
            propertySize = GetPropertyByNameW(model, L"size"),
            propertySegmentationParts = GetPropertyByNameW(model, L"segmentationParts");

    //
    //  Instances (creating)
    //
    int64_t myInstanceArc3D = CreateInstanceW(classArc3D, nullptr);

    double  Pi = 2. * acos(0.),
            radius = 2.1,
            start = 0.,
            size = 2. * Pi;
    int64_t segmentationParts = 36;
        
    SetDatatypeProperty(myInstanceArc3D, propertyRadius, &radius, 1);
    SetDatatypeProperty(myInstanceArc3D, propertyStart, &start, 1);     //  in this case we could also do without, i.e. default value
    SetDatatypeProperty(myInstanceArc3D, propertySize, &size, 1);       //  in this case we could also do without, i.e. default value
    SetDatatypeProperty(myInstanceArc3D, propertySegmentationParts, &segmentationParts, 1);

    //
    //  The resulting model can be viewed in 3D-Editor.exe
    //
    SaveModelW(model, L"c:\\created\\myFile.bin");
    CloseModel(model);
