Interface IConsumerContainerSelector

All Known Implementing Classes:

ConsumerContainerSelector

public interface IConsumerContainerSelector

Consumer container selector service contract. When an ECF RemoteServiceAdmin instance is asked to import a service (i.e. via RemoteServiceAdmin.importService(org.osgi.service.remoteserviceadmin.EndpointDescription) ), the RSA first gets an instance of this service via the service registry, and then uses it to select an ECF consumer container instance by calling selectConsumerContainer(EndpointDescription).

The IRemoteServiceContainer returned is then used on the consumer side, to actually import the remote service.

If no other instances of this service have been registered, a default instance of ConsumerContainerSelector will be used. Note that this default instance is registered with the lowest possible priority, so that if other IConsumerContainerSelector instances are registered, they will be preferred/used over the default.
