Connection Point Classes

ATL uses the following classes to support connection points:

• IConnectionPointImpl implements a connection point. The IID of the outgoing interface it represents is passed as a template parameter.
  
  
• IConnectionPointContainerImpl implements the connection point container and manages the list of IConnectionPointImpl objects.
  
  
• IPropertyNotifySinkCP implements a connection point representing the IPropertyNotifySink interface.
  
  
• CComDynamicUnkArray manages an arbitrary number of connections between the connection point and its sinks.
  
  
• CComUnkArray manages a predefined number of connections as specified by the template parameter.
  
  
• CFirePropNotifyEvent notifies a client's sink that an object's property has changed or is about to change.
