CreateProperty
If the model input is zero or not a model handle 0 will be returned,
Syntax
// Visual Studio for Windows public: __int64 __declspec(dllexport) __stdcall CreateProperty( __int64 model, __int64 rdfPropertyType, const char * name ); // Linux, OS-X and non-Visual Studio Windows solutions public: int64_t CreateProperty( int64_t model, int64_t rdfPropertyType, const char * name );
Property model
Size: 64 bit / 8 byte (value)Property rdfPropertyType
Size: 64 bit / 8 byte (value)Property name
Size: 64 bit / 8 byte (reference)
Example
Here you can find code snippits that show how the API call CreateProperty can be used.
#includeint64_t model = CreateModel(); if (model) { // // Classes // int64_t classCollection = GetClassByName(model, "Collection"), classCube = GetClassByName(model, "Cube"); // // Object Properties (relations) // int64_t propertyAbcd = CreateProperty(model, OBJECTPROPERTY_TYPE, "abcd"), propertyObjects = GetPropertyByName(model, "objects"); // // Datatype Properties (attributes) // int64_t propertyLength = GetPropertyByName(model, "length"), propertyEfgh = CreateProperty(model, DATATYPEPROPERTY_TYPE_DOUBLE, "efgh"); // // Instances (creating) // int64_t instanceCollection = CreateInstance(classCollection, nullptr), instanceCube = CreateInstance(classCube, nullptr); double length = 2., efgh = 1.7; SetDatatypeProperty(instanceCube, propertyLength, &length, 1); SetDatatypeProperty(instanceCollection, propertyEfgh, &efgh, 1); assert(GetVolume(instanceCollection, 0, 0) == 0.); char * propertyNameI = nullptr; GetNameOfProperty(propertyAbcd, &propertyNameI); char * propertyNameII = nullptr; GetNameOfProperty(propertyEfgh, &propertyNameII); SetNameOfProperty(propertyAbcd, "InverseRelationControledByThirdParty"); SetObjectProperty(instanceCube, propertyAbcd, &instanceCollection, 1); SetObjectProperty(instanceCollection, propertyObjects, &instanceCube, 1); assert(GetVolume(instanceCollection, 0, 0) == 8.); char * propertyNameIII = nullptr; GetNameOfProperty(propertyAbcd, &propertyNameIII); // // The retrieved property names have the following values // propertyNameI : 'abcd' // propertyNameII : 'efgh' // propertyNameIII : 'InverseRelationControledByThirdParty' // // // The resulting model can be viewed in 3D-Editor.exe // SaveModel(model, "c:\\created\\myFile.bin"); CloseModel(model); }
