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));

- intoResultGroups
  
  public static final <K, R extends Record> Collector<R,?,Map<K,Result<R>>> intoResultGroups(Function<? super R,? extends K> keyMapper)
  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 records themselves into a Result.
  For example:
  
  Map<Integer, Result<Record2<Integer, String>>> books = ctx.select(BOOK.ID, BOOK.TITLE) .from(BOOK) .collect(intoResultGroups(r -> r.get(BOOK.ID)));
  
  This is the same as the following:
  
  Map<Integer, Result<Record2<Integer, String>>> books = ctx.select(BOOK.ID, BOOK.TITLE) .from(BOOK) .fetchGroups(BOOK.ID);
- intoResultGroups
  
  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)));
  
  This is the same as the following:
  
  Map<Integer, Result<Record1<String>>> books = ctx.select(BOOK.ID, BOOK.TITLE) .from(BOOK) .fetchGroups(BOOK.ID, BOOK.TITLE);
- intoHierarchy
  
  public static final <K, E, R extends Record> Collector<R,?,List<E>> intoHierarchy(Function<? super R,? extends K> keyMapper, Function<? super R,? extends K> parentKeyMapper, Function<? super R,? extends E> nodeMapper, BiConsumer<? super E,? super E> parentChildAppender)
  Create a collector that can collect Record resulting from a ResultQuery into a hierarchy of custom data types.
  For example:
  
  record File(String name, List<File> contents) {} List<File> files = ctx.select(FILE.ID, FILE.PARENT_ID, FILE.NAME) .from(FILE) .collect(intoHierarchy( r -> r.value1(), r -> r.value2(), r -> new File(r.value3(), new ArrayListinvalid input: '<'>()), (p, c) -> p.contents().add(c) ));
  Type Parameters:
  
  K - The key type (e.g. an ID)
  
  E - The value type (e.g. a POJO)
  
  R - The record type
  
  Parameters:
  
  keyMapper - A function that extract a key from a record
  
  parentKeyMapper - A function that extracts the parent key from a record.
  
  nodeMapper - A function that maps a record to a new value type.
  
  parentChildAppender - A (parent, child) consumer that adds the child to its parent.

  Create a RecordMapper that turns Record values containing any null value into a null record value.
  This is useful, for example, when nesting records from implicit path joins following optional foreign keys, where a (NULL, NULL, …, NULL) record isn't so useful.
