ICollectionOnSTLImpl Class

Visual Studio 2012

This class provides methods used by a collection class.

template < 
   class T, 
   class CollType, 
   class ItemType, 
   class CopyItem, 
   class EnumType 
> 
class ICollectionOnSTLImpl : 
   public T

Name	Description
ICollectionOnSTLImpl::get__NewEnum	Returns an enumerator object for the collection.
ICollectionOnSTLImpl::get_Count	Returns the number of elements in the collection.
ICollectionOnSTLImpl::get_Item	Returns the requested item from the collection.

Name	Description
ICollectionOnSTLImpl::m_coll	The collection.

This class provides the implementation for three methods of a collection interface: get_Count, get_Item, and get__NewEnum.

To use this class:

Define (or borrow) a collection interface that you wish to implement.
Derive your class from a specialization of ICollectionOnSTLImpl based on this collection interface.
Use your derived class to implement any methods from the collection interface not handled by ICollectionOnSTLImpl.

Note
If the collection interface is a dual interface, derive your class from IDispatchImpl, passing the ICollectionOnSTLImpl specialization as the first template parameter if you want ATL to provide the implementation of the IDispatch methods.

For more information and examples, see ATL Collections and Enumerators.
