Provides stream-oriented diagnostic output in text form for the elements of your collection when overridden.
template<class TYPE> void AFXAPI DumpElements( CDumpContext& dc, const TYPE* pElements, INT_PTR nCount );
The CArray::Dump, CList::Dump, and CMap::Dump functions call this if the depth of the dump is greater than 0.
The default implementation does nothing. If the elements of your collection are derived from CObject, your override will typically iterate through the collection's elements, calling Dump for each element in turn.
