Interface ISynchronizationScopeChangeListener
-
All Superinterfaces:
-
EventListener
-
public interface ISynchronizationScopeChangeListener
- extends
EventListener
Listener for synchronization scope changes.
Clients may implement this interface.
-
Since:
- 3.2

ISynchronizationScope
scopeChanged
void scopeChanged(
ISynchronizationScope scope,
ResourceMapping[] mappings,
ResourceTraversal[] traversals)
- Notification that the scope has changed. The change may be the inclusion
of new resource mappings, new resource traversals or both or the removal
of mappings (in which case the given traversals will cover the set of
resources that are no longer in the scope). This can be due to changes to
the resource mappings used to calculate the traversals of the scope or
because new resources have come under the control of the repository
provider (or other entity) that generated the scope in the first place.
Clients can determine whether a given mappings were removed by querying
the scope for traversals. If the mapping has no traversals, the mapping
represents a removal.
Clients can use the following rules to interpret the change:
- If the mappings are not empty, clients should check to see if the
the scope contains traversals for the any of the mappings. If it does,
the given mappings have been added to the scope. If it doesn't the
mappings represent removals. A change event will never include both new
and removed mappings.
- If the mappings are added mappings, and the traversals are empty,
then the addition of the mappings did not change the resources covered by
the scope.
- If the mappings are added mappings, and the traversals are not
empty, then the additional mappings also caused additional resources to
be included in the scope. The given traversals cover the resources that
have been added to the scope.
- If the mappings are removed mappings, and the traversals are not
empty, then the removed mappings also caused resources to be removed from
the scope. The given traversals cover the resources that have been
removed to the scope.
- If the mappings are empty and the traversals are not, the traversals
cover resources that have been added to the scope due to a change in the
logical model or the resource under the control of the repository
providers that manages the scope.
