<p>Casts a derived class to its non-virtual base class in a way that safely supports abstract classes. </p>
|
|
<p>This should be used in cases when a derived type needs to serialize its base type. This is better than directly using static_cast, as it allows for serialization of pure virtual (abstract) base classes.</p>
