Name Description
IConnectionPointContainerImpl::EnumConnectionPoints Creates an enumerator to iterate through the connection points supported in the connectable object.
IConnectionPointContainerImpl::FindConnectionPoint Retrieves an interface pointer to the connection point that supports the specified IID.

Remarks

IConnectionPointContainerImpl implements a connection point container to manage a collection of IConnectionPointImpl objects. IConnectionPointContainerImpl provides two methods that a client can call to retrieve more information about a connectable object:

  • EnumConnectionPoints allows the client to determine which outgoing interfaces the object supports.

  • FindConnectionPoint allows the client to determine whether the object supports a specific outgoing interface.

For information about using connection points in ATL, see the article Connection Points.
