Examples of org.hibernate.metamodel.relational.Tuple

org.hibernate.metamodel.relational.Tuple
Models a compound value (a tuple or row-value-constructor is SQL terms). It is both a {@link Value} anda {@link ValueContainer} simultaneously.
IMPL NOTE : in terms of the tables themselves, SQL has no notion of a tuple/compound-value. We simply model it this way because:
- it is a cleaner mapping to the logical model
- it allows more meaningful traversals from simple values back up to table through any intermediate tuples because it gives us a better understanding of the model.
- it better conveys intent
- it adds richness to the model
