org.apache.felix.dm.tracker.ServiceTracker
The ServiceTracker class simplifies using services from the Framework's service registry.
A ServiceTracker object is constructed with search criteria and a ServiceTrackerCustomizer object. A ServiceTracker can use a ServiceTrackerCustomizer to customize the service objects to be tracked. The ServiceTracker can then be opened to begin tracking all services in the Framework's service registry that match the specified search criteria. The ServiceTracker correctly handles all of the details of listening to ServiceEvents and getting and ungetting services.
The getServiceReferences method can be called to get references to the services being tracked. The getService and getServices methods can be called to get the service objects for the tracked service.
The ServiceTracker class is thread-safe. It does not call a ServiceTrackerCustomizer while holding any locks. ServiceTrackerCustomizer implementations must also be thread-safe. @ThreadSafe @version $Revision: 6386 $
