Interface LinkedHashMapRowReducer<K,V>

Type Parameters:

K - the map key type--often the primary key type of <V>.

V - the map value type, and the result element type--often the "master" object in a master/detail relation.

All Superinterfaces:

RowReducer<Map<K,V>,V>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface LinkedHashMapRowReducer<K,V>
extends RowReducer<Map<K,V>,V>

A row reducer that uses LinkedHashMap (which preserves insertion order) as a result container, and returns map.values().stream() as the final result.

Implementors need only implement the RowReducer.accumulate(Object, RowView) method.

Method Summary

Modifier and Type	Method and Description
default Map<K,V>	container() Returns a new, empty result container.
default Stream<V>	stream(Map<K,V> container) Returns a stream of result elements from the result container.
