Imports
org.hibernate.Incubating, org.hibernate.sql.results.internal.RowTransformerTupleTransformerAdapter, java.util.List
Defines some transformation applied to each result of a Query before the results are packaged as a List and returned to the caller. Each result is received as a tuple (that is, as an Object[]), and may be transformed to some other type.

Implementation Note

Every TupleTransformer is automatically wrapped in an instance of RowTransformerTupleTransformerAdapter, adapting it to the org.hibernate.sql.results.spi.RowTransformer contract, which is always used to actually process the results internally.
