```
@Experimental
public interface CaseEventCreationListener
```
An interface through which external observers can be notified about case-related events. Used to implement case-related notifications. It is here to avoid a dependency of case-impl (i.e. the producer of change notification events) on notification-impl (where change events are implemented). In the future, the specific events (case, model, resource objects, ...) PROBABLY will be implemented in the respective modules (case-impl, model-impl, provisioning-impl, etc). Then this interface will disappear.

Method Detail

onCaseOpening

void onCaseOpening(CaseType aCase,
                   Task task,
                   OperationResult result)

This method is called by cases module when a case is opened.

Parameters:: result - implementer should report its result here

onCaseClosing
```
void onCaseClosing(CaseType aCase,
                   Task task,
                   OperationResult result)
```
This method is called by cases module when a case is being closed. (There is an uncertainty about closing vs closed state.)

Parameters:
