Detailed Description

template<typename SelectableType>
class engine::SafeSelectable< SelectableType >

Holds a pointer to some type of Selectable, which automatically becomes null if the selectable is deleted.

The SelectableType template parameter must be Selectable, or some subclass of Selectable.
