Both of these points can be dealt with using a lifestyle manager. The
current implemetation does not currently provide support for the
Selector interface - instead selection policy is provided to the
container and the client will receive the preferred selection based on
the supplied policy. A second reason is that the policy of appending the
string "Selector" to an interface as the means though which policy is
declared to a container is inconsitent with the concept of component
scoped role names. Finally, logical concerning selection can be far
reaching - Merlin provides support for the dynamic creation of
components, different component profiles, programmatically constructured
component profiles, etc. Simply requesting all know services of a
particular type under a component selector forces the instantiation of
all candidate profiles - whereas supplying the selection policy enables
the container to do the selection without actually instantiating the
component - in fact components are not normally instantiated until the
client actually invokes lookup on the component or service manager.
