Examples of org.hibernate.ogm.datastore.spi.Tuple

org.hibernate.ogm.datastore.spi.Tuple
Represents a Tuple (think of it as a row) A tuple accepts a TupleShapshot which is a read-only state of the tuple at creation time. A tuple collects changes applied to it. These changes are represented by a list of TupleOperation. It is intended that GridDialects retrieve to these actions and reproduce them to the datastore. The list of changes is computed based off the snapshot. @author Emmanuel Bernard <emmanuel@hibernate.org> @author Sanne Grinovero <sanne@hibernate.org>
