Methods
The IConnectionPoint interface has these methods.
| IConnectionPoint::Advise Establishes a connection between a connection point object and the client's sink. |
| IConnectionPoint::EnumConnections Creates an enumerator object to iterate through the current connections for this connection point. |
| IConnectionPoint::GetConnectionInterface Retrieves the IID of the outgoing interface managed by this connection point. |
| IConnectionPoint::GetConnectionPointContainer Retrieves the IConnectionPointContainer interface pointer for the parent connectable object. |
| IConnectionPoint::Unadvise Terminates an advisory connection previously established between a connection point object and a client's sink. |
Remarks
Connectable objects support the following features:
- Outgoing interfaces, such as event sets
- The ability to enumerate the IIDs of the outgoing interfaces
- The ability to connect and disconnect sinks to the object for those outgoing IIDs
- The ability to enumerate the connections that exist to a particular outgoing interface
