Detailed Description

template<typename ReturnPointer, typename OriginalPointer, CountedPointerCastingState>
class Mezzanine::CountedPtrCastImpl< ReturnPointer, OriginalPointer, CountedPointerCastingState >

This is used as to determine how a CountedPtr performs castin between pointer types internally.

The default implementation for internal casting in the CountedPtr Simply throws an exception.

This Should never actually get called. Though it is the default template instance the default ReferenceCountTraits uses the CastNoneError specialization of this template.

The ReferenceCountTraits for the CountedPtr<Type> should declare what kind castint should be used by declaring an enumeration called 'IsCastable' and assigning the desired casting type.

enum { IsCastable = CastStaticVirtual };

Template Parameters

ReturnPointer	The type of pointer that the functions on the CountedPtr must return
OriginalPointer	The actual type the CountedPtr is maintaining as a target.
CountedPointerCastingState	Any value in the CountedPointerCastingState to indicate kind of casting.

For any case that uses CastNoneError including the default.
