public final class Records extends Object

Common utilities related to Record types and constructing RecordMapper.

The various mapping() methods can be used e.g. to map between Record types and constructors of known degree, such as in this example:


 record Actor (int id, String firstName, String lastName) {}

 List<Actor> actors =
 ctx.select(ACTOR.ID, ACTOR.FIRST_NAME, ACTOR.LAST_NAME)
    .from(ACTOR)
    .fetch(mapping(Actor::new));

  public static final <K, V extends Record, R extends Record> Collector<R,?,Map<K,Result<V>>> intoResultGroups(Function<? super R,? extends K> keyMapper, Function<? super R,? extends V> valueMapper)
  Create a collector that can collect Record resulting from a ResultQuery into a Map using the result of the argument RecordMapper as key collecting the result of another argument RecordMapper into a Result of values.
  For example:
  
  Map<Integer, Result<Record1<String>>> books = ctx.select(BOOK.ID, BOOK.TITLE) .from(BOOK) .collect(intoResultGroups(r -> r.get(BOOK.ID), r -> r.get(BOOK.TITLE)));
