Examples of org.hibernate.ogm.jdbc.impl.TupleAsMapResultSet

org.hibernate.ogm.jdbc.impl.TupleAsMapResultSet
Implements JDBC's ResultSet interface but is essentially a wrapper for propagating a list of {@code Map} that reach represent a tuple.
The ResultSet implementation is close to none (don't use it as a regular ResultSet) - currently only implement next() for moving along the set of tuples - implements unwrap / isWrapperFor for TupleAsMapResultSet.class
Otherwise, to add a tuple, use addTuple. To read the current tuple, use getTuple() To move forward, use next() (throws a SQLException, I know that sucks) @author Emmanuel Bernard
