    public abstract class FSComponentExtRepositoryDB<FSCRC extends FSCRDBComponent>
extends java.lang.Object
implements java.io.Serializable
    A utility for component repository implementers. This helps implementing the index of components provided and query functionality (see IComponentsRepository.findComponents(X) as well as a simple query cache. This class is not thread safe.
