java.lang.Object

org.apache.felix.ipojo.dependency.interceptors.DefaultDependencyInterceptor

org.apache.felix.ipojo.dependency.interceptors.DefaultServiceTrackingInterceptor

All Implemented Interfaces:

DependencyInterceptor, ServiceTrackingInterceptor

public class DefaultServiceTrackingInterceptor
extends DefaultDependencyInterceptor
implements ServiceTrackingInterceptor

Default implementation of the default service tracking interceptor. It accepts all references and keeps the dependencies in the `dependencies` list. This list is guarded by the monitor lock. It also provides an `invalidateMatchingServices` method notifying all managed dependencies of a change in the matching service set.

Method Detail

accept

public <S> TransformedServiceReference<S> accept(DependencyModel dependency,
                                                 org.osgi.framework.BundleContext context,
                                                 TransformedServiceReference<S> ref)

Default implementation of the accept method. The default behavior is to accept all services as they are (no transformation).

Specified by:

accept in interface ServiceTrackingInterceptor

Type Parameters:

S - the type of service

Parameters:

dependency - the dependency the dependency

context - the context of the dependency the bundle context used by the dependency

ref - the reference the reference to accept, transform or reject

Returns:

the reference as it is.

invalidateMatchingServices

public void invalidateMatchingServices()

Notifies the managed dependencies of a change in the set of services accepted by this interceptor. The dependency will call the accept method to recompute the set of matching services.
