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
public const string EngineDLL = @"engine.dll";[DllImport(EngineDLL, EntryPoint = "GetInstanceClass")] public static extern Int64 GetInstanceClass(Int64 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.
using Engine; static void Main(string[] args) { Int64 model = Engine.x86_64.CreateModel(); if (model != 0) { // // Classes // Int64 classAbcd = Engine.x86_64.CreateClass(model, "ABCD"), classCube = Engine.x86_64.CreateClass(model, "Cube"), classMatrix = Engine.x86_64.CreateClass(model, "Matrix"); // // Instances // Int64 instanceAbcd = Engine.x86_64.CreateInstance(classAbcd, (string) null), instanceCube = Engine.x86_64.CreateInstance(classCube, (string) null), instanceMatrixI = Engine.x86_64.CreateInstance(classMatrix, (string) null), instanceMatrixII = Engine.x86_64.CreateInstance(classMatrix, (string) null); System.Diagnostics.Debug.Assert(Engine.x86_64.GetInstanceClass(instanceAbcd) == classAbcd); System.Diagnostics.Debug.Assert(Engine.x86_64.GetInstanceClass(instanceCube) == classCube); System.Diagnostics.Debug.Assert(Engine.x86_64.GetInstanceClass(instanceMatrixI) == Engine.x86_64.GetInstanceClass(instanceMatrixII)); // // The resulting model can be viewed in 3D-Editor.exe // Engine.x86_64.SaveModel(model, "c:\\created\\myFile.bin"); Engine.x86_64.CloseModel(model); } }
