getReference
Description copied from interface:ServiceRegistration
Returns aServiceReference
object for a service being registered.The
ServiceReference
object may be shared with other bundles.- Specified by:
getReference
in interfaceServiceRegistration
- Returns:
ServiceReference
object.
-
setProperties
Description copied from interface:ServiceRegistration
Updates the properties associated with a service.The
Constants.OBJECTCLASS
,Constants.SERVICE_BUNDLEID
,Constants.SERVICE_ID
andConstants.SERVICE_SCOPE
keys cannot be modified by this method. These values are set by the Framework when the service is registered in the OSGi environment.The following steps are required to modify service properties:
- The service's properties are replaced with the provided properties.
- A service event of type
ServiceEvent.MODIFIED
is fired.
- Specified by:
setProperties
in interfaceServiceRegistration
- Parameters:
dict
- The properties for this service. SeeConstants
for a list of standard service property keys. Changes should not be made to this object after calling this method. To update the service's properties this method should be called again.
-
unregister
public void unregister()Description copied from interface:ServiceRegistration
Unregisters a service. Remove aServiceRegistration
object from the Framework service registry. AllServiceReference
objects associated with thisServiceRegistration
object can no longer be used to interact with the service once unregistration is complete.The following steps are required to unregister a service:
- The service is removed from the Framework service registry so that it can no longer be obtained.
- A service event of type
ServiceEvent.UNREGISTERING
is fired so that bundles using this service can release their use of the service. Once delivery of the service event is complete, theServiceReference
objects for the service may no longer be used to get a service object for the service. - For each bundle whose use count for this service is greater than
zero:
- The bundle's use count for this service is set to zero.
- If the service was registered with a
ServiceFactory
object, theServiceFactory.ungetService
method is called to release the service object for the bundle.
- Specified by:
unregister
in interfaceServiceRegistration

-
isClassAccessible
This method determines if the class loader of the service object has access to the specified class.- Parameters:
clazz
- the class to test for reachability.- Returns:
- true if the specified class is reachable from the service object's class loader, false otherwise.
