The _ICATollsEvents interface is an outgoing connection-point interface, used by the ICATolls collection. The Conditional Access (CA) Manager forwards these events through the _ICAManagerEvents interface, so it might be easier to use that interface instead.
To receive events from an ICATolls collection, implement this interface. Then call the IConnectionPoint::Advise method to establish a connection.
_ICATollsEvents is a dispinterface, invoked through IDispatch. It supports the following methods.
| Method | Description |
| ItemAdded | Called when a toll is added to a collection. |
| ItemRemoved | Called when a toll is removed from a collection. |
| StateChanged | Called when the state of a toll changes. |
