A connectable object is one that supports outgoing interfaces. An outgoing interface allows the object to communicate with a client. For each outgoing interface, the connectable object exposes a connection point. Each outgoing interface is implemented by a client on an object called a sink.

Each connection point supports the IConnectionPoint interface. The connectable object exposes its connection points to the client through the IConnectionPointContainer interface.
