Method Detail

addingService

public RefPair<S,T> addingService(org.osgi.framework.ServiceReference<T> serviceReference)

Description copied from interface: ServiceTrackerCustomizer

A service is being added to the ServiceTracker.

This method is called before a service which matched the search parameters of the ServiceTracker is added to the ServiceTracker. This method should return the service object to be tracked for the specified ServiceReference. The returned service object is stored in the ServiceTracker and is available from the getService and getServices methods.

Parameters:

serviceReference - The reference to the service being added to the ServiceTracker.

Returns:

The service object to be tracked for the specified referenced service or null if the specified referenced service should not be tracked.

addedService

public void addedService(org.osgi.framework.ServiceReference<T> serviceReference,
                         RefPair<S,T> refPair,
                         int trackingCount,
                         int serviceCount,
                         ExtendedServiceEvent event)

modifiedService

public void modifiedService(org.osgi.framework.ServiceReference<T> serviceReference,
                            RefPair<S,T> refPair,
                            int trackingCount,
                            ExtendedServiceEvent event)

Description copied from interface: ServiceTrackerCustomizer

A service tracked by the ServiceTracker has been modified.

This method is called when a service being tracked by the ServiceTracker has had it properties modified.

Parameters:

serviceReference - The reference to the service that has been modified.

refPair - The service object for the specified referenced service.

event - TODO

removedService

public void removedService(org.osgi.framework.ServiceReference<T> serviceReference,
                           RefPair<S,T> refPair,
                           int trackingCount,
                           ExtendedServiceEvent event)

Description copied from interface: ServiceTrackerCustomizer

A service tracked by the ServiceTracker has been removed.

This method is called after a service is no longer being tracked by the ServiceTracker.

Parameters:

serviceReference - The reference to the service that has been removed.

refPair - The service object for the specified referenced service.

event - TODO

prebind

public boolean prebind(ComponentContextImpl<S> key)

Description copied from interface: DependencyManager.Customizer

attempt to obtain the services from the tracked service references that will be used in inital bind calls before activation.

Parameters:

key - TODO

Returns:

true if there are enough services for activation.

close

public void close()

closeRefPair

private void closeRefPair()

getRefs

public java.util.Collection<RefPair<S,T>> getRefs(java.util.concurrent.atomic.AtomicInteger trackingCount)
