org.apache.felix.ipojo.dependency.interceptors.ServiceTrackingInterceptor
A service to influence the visibility of services within a service dependency. This service is called to determine which services from the tracker (base set) is going to the matching set. Several tracking interceptors can be plugged to the same service dependency. In this case, a chain is created where all interceptor can influence the next one. If the dependency has a filter, a tracking interceptor using this filter is the last interceptor of the chain. Obviously an interceptor can be plugged to several dependencies. Conversely, several tracking interceptor can be plugged to one dependency. @since 1.10.1
