  24. * from a collections. {@link Expression} is crafted in a way that you can
  25. * implement queries from both in-memory and database-backed collections.
  26. *
  27. * For database backed collections this allows very efficient access by
  28. * utilizing the query APIs, for example SQL in the ORM. Applications using
  29. * this API can implement efficient database access without having to ask the
  30. * EntityManager or Repositories.
