Interface ServiceManager

All Known Implementing Classes:

StandardServiceManager

public interface ServiceManager

The ServiceManager is used to manage uniqueness of services and runtime discovery of service implementations.

Uniqueness is meant in the scope of the SearchFactory, as there is a single ServiceManager instance per SearchFactory.

Any service requested should be released using releaseService(Class) when it's not needed anymore.
