[osg-users] Serialization with virtual base classes

[Julien Valentin]

Hi Hartwig
I believe the best way to understand osg metamodel is study existing serializers in src/osgWrappers/serializers/osg/
In the case of virtual base class you'll have to set OBJECT_CAST macro to dynamic_cast
see https://github.com/openscenegraph/OpenSceneGraph/blob/master/src/osgWrappers/serializers/osg/Callback.cpp for an example
The string in serializer with multiple class name is called the associate list:
it refers to all other serializers that should be invoked (basically all base serializers must be mentionned)
Hope it helps

Happy Xmas
