Can be overridden by subclasses to customize RepositoryComposition.RepositoryFragments.

Parameters:

metadata - repository metadata.

entityManager - the entity manager.

resolver - resolver to translate an plain domain class into a EntityPath.

crudMethodMetadata - metadata about the invoked CRUD methods.
