ATL中集合和枚举器

一.实现枚举器

typedef std::vector< std::string >                ContainerType;
typedef VCUE::GenericCopy<VARIANT, ContainerType::value_type>        EnumeratorCopyType;
typedef CComEnumOnSTL< IEnumVARIANT, &__uuidof(IEnumVARIANT), VARIANT,
                        EnumeratorCopyType, ContainerType > EnumeratorType;

二.实现ICollection

typedef VCUE::GenericCopy<BSTR, ContainerType::value_type>        CollectionCopyType;
typedef ICollectionOnSTLImpl<IWords, ContainerType,BSTR,
                        CollectionCopyType,EnumeratorType> CollectionType;
