GetInstanceClass
Note: internally this function is not rich enough as support for multiple inheritance
is making it impossible to answer this request with always one class handle.
Even in the case of pure single inheritance an instance of a class is also an instance of
every parent classes in the inheritance tree. For now we expect single inheritance use
and the returned class handle points to the 'lowest' class in the inheritance tree.
Syntax
// Visual Studio for Windows public: __int64 __declspec(dllexport) __stdcall GetInstanceClass( __int64 owlInstance ); // Linux, OS-X and non-Visual Studio Windows solutions public: int64_t GetInstanceClass( int64_t owlInstance );
Property owlInstance
Size: 64 bit / 8 byte (value)
Example
Here you can find code snippits that show how the API call GetInstanceClass can be used.
int64_t model = CreateModel(); if (model) { // // Classes // int64_t classAbcd = CreateClass(model, "ABCD"), classCube = CreateClass(model, "Cube"), classMatrix = CreateClass(model, "Matrix"); // // Instances // int64_t instanceAbcd = CreateInstance(classAbcd, nullptr), instanceCube = CreateInstance(classCube, nullptr), instanceMatrixI = CreateInstance(classMatrix, nullptr), instanceMatrixII = CreateInstance(classMatrix, nullptr); assert(GetInstanceClass(instanceAbcd) == classAbcd); assert(GetInstanceClass(instanceCube) == classCube); assert(GetInstanceClass(instanceMatrixI) == GetInstanceClass(instanceMatrixII)); // // The resulting model can be viewed in 3D-Editor.exe // SaveModel(model, "c:\\created\\myFile.bin"); CloseModel(model); }
