Examples of com.volantis.osgi.cm.factory.FactoryAssociation

com.volantis.osgi.cm.factory.FactoryAssociation
Represents the association between a number (usually one) of {@link ManagedServiceFactory} instances and a number of configurations.
The association is bound to a particular bundle only when a {@link ManagedServiceFactory} with a matching factory PID is registered. Until thenit remains unbound. The configurations however, may be bound either when they are created through the admin service, or when the association is bound. The configurations can be bound to different locations to the association. In this situation only those configurations that are bound to the correct location are passed to the factory. The others are just ignored.
