Class Collector<R>

java.lang.Object

org.nuiton.topia.persistence.legacy.Collector<R>

Type Parameters:

R - les donnes a retourner

public abstract class Collector<R>
extends Object

Un objet qui permet de parcourir des entites (via un Collector.CollectorVisitor) et de collecter des donnees pendant le parcours.

La classe a un type qui est le type de retour de la methode detect(TopiaEntity...).

On peut donc très facilement en faire un collecteur de donnees.

Since:

2.2.0
