						|
								 *
							 | 
						|
								 * copy_enumerator_impl is the analogue to CComEnumImpl, but the advantages
							 | 
						|
								 * over the ATL class is that it can be added to/removed from after
							 | 
						|
								 * initialisation, and it can be initialised/appended from a sequence (as
							 | 
						|
								 * defined by the start and end iterators), rather than assuming an array as
							 | 
						|
								 * source.
							 | 
						|
								 *
							 | 
						|
								 * copy_enumerator is the analogue to CComEnum, but uses the
							 | 
						|
								 * atlstl::copy_enumerator_impl as its 'implementation' class template.
							 | 
						|
								 *
							 | 
						|
								 * \param I The interface, e.g. IEnumString
							 | 
						|
								 * \param piid The address of the interface, e.g. &IID_IEnumString
							 | 
						|
								 * \param V The value type of the enumeration, e.g. LPOLESTR
							 | 
						|
								 * \param It The iterator class, e.g. LPOLESTR*
							 | 
						|
								 * \param Copy A class that implements copy behaviour (see CComEnumImpl)
							 | 
						|
								 * \param ThreadModel The threading model of the instances (see CComObjectRoot)
							 | 
						|
								 *
							 | 
						|
								 * \note The copy_enumerator_impl class only supports copy semantics on the
							 | 
						|
								 * Init and Add methods, i.e. it always creates its enumeration contents by
							 | 
						|
								 * taking a copy of the contents of its source.
