Public Member Functions
	WeakArrayPtr ()
	Construct a null weak array pointer.
	WeakArrayPtr (const WeakArrayPtr< T > &rhs)
	Copy-construct from another weak array pointer.
	WeakArrayPtr (const SharedArrayPtr< T > &rhs)
	Construct from a shared array pointer.
	~WeakArrayPtr ()
	Destruct. Release the weak reference to the array.
WeakArrayPtr< T > &	operator= (const SharedArrayPtr< T > &rhs)
	Assign from a shared array pointer.
WeakArrayPtr< T > &	operator= (const WeakArrayPtr< T > &rhs)
	Assign from another weak array pointer.
SharedArrayPtr< T >	Lock () const
	Convert to shared array pointer. If expired, return a null shared array pointer.
T *	Get () const
	Return raw pointer. If expired, return null.
T *	operator-> () const
	Point to the array.
T &	operator* () const
	Dereference the array.
T &	operator[] (const int index)
	Subscript the array.
bool	operator== (const WeakArrayPtr< T > &rhs) const
	Test for equality with another weak array pointer.
bool	operator!= (const WeakArrayPtr< T > &rhs) const
	Test for inequality with another weak array pointer.
bool	operator< (const WeakArrayPtr< T > &rhs) const
	Test for less than with another weak array pointer.
	operator T* () const
	Convert to a raw pointer, null if array is expired.
void	Reset ()
	Reset to null and release the weak reference.
template<class U >
void	StaticCast (const WeakArrayPtr< U > &rhs)
	Perform a static cast from a weak array pointer of another type.
template<class U >
void	DynamicCast (const WeakArrayPtr< U > &rhs)
	Perform a dynamic cast from a weak array pointer of another type.
bool	Null () const
	Check if the pointer is null.
bool	NotNull () const
	Check if the pointer is not null.
int	Refs () const
	Return the array's reference count, or 0 if null pointer or if array has expired.
int	WeakRefs () const
	Return the array's weak reference count.
bool	Expired () const
	Return whether the array has expired. If null pointer, always return true.
RefCount *	RefCountPtr () const
	Return pointer to RefCount structure.
unsigned	ToHash () const
	Return hash value for HashSet & HashMap.

Private Member Functions
template<class U >
WeakArrayPtr< T > &	operator= (const WeakArrayPtr< U > &rhs)
	Prevent direct assignment from a weak array pointer of different type.
void	AddRef ()
	Add a weak reference to the array pointed to.
void	ReleaseRef ()
	Release the weak reference. Delete the Refcount structure if necessary.

Private Attributes
T *	ptr_
	Pointer to the array.
RefCount *	refCount_
	Pointer to the RefCount structure.
