Class PermissionGatherer

java.lang.Object
  org.apache.clerezza.permissiondescriptions.PermissionGatherer

All Implemented Interfaces:

EventListener, org.osgi.framework.BundleListener

@Service(value=PermissionGatherer.class)
@Reference(name="permissionProvider",
           policy=DYNAMIC,
           referenceInterface=PermissionDescriptionsProvider.class,
           cardinality=OPTIONAL_MULTIPLE)
public class PermissionGatherer
extends Object
implements org.osgi.framework.BundleListener

This binds all implementations of PermissionDescriptionsProvider, and gathers their PermissionDescriptions. Furthermore the gatherer scans all activaded bundles for Permissions which are annonated with the PermissionInfo annotation and generates PermissionDescriptions for them. This service provides methods to retrieve the gathered PermissionDescriptions and also methods to retrieve all unannotated Permission found in the activated bundles. If new bundles are started then they are also scanned.
