Detailed Description

Derive from RefCounted if you want to enable reference counting of this class.

If you want to use automatic reference counting, you should use RefCountingPtr<T> instead of regular pointers.

Constructor & Destructor Documentation

RefCounted::RefCounted ( const RefCounted &  )

private

RefCounted::RefCounted ( )

inline

We initialize the reference count to zero and the first object to take ownership of it must increment it to one.

Attention

A memory leak will occur if you never assign a newly constructed object to a reference counting pointer.

Definition at line 69 of file refcnt.hh.

virtual RefCounted::~RefCounted ( )

inlinevirtual

We make the destructor virtual because we're likely to have virtual functions on reference counted objects.

Todo:

Even if this were true, does it matter? Shouldn't the derived class indicate this? This only matters if we would ever choose to delete a "RefCounted *" which I doubt we'd ever do. We don't ever delete a "void *".
