Class Quadruple<A,B,C,D>

Object

com.net2plan.utils.Quadruple<A,B,C,D>

public class Quadruple<A,B,C,D>
extends Object

A quadruple consisting of four elements. There is no restriction on the type of the objects that may be stored.

Example:

Map<String, Object> map = new HashMap<>();
map.put("parameter", "value");
Integer number = new Integer(3);
String string = "Test";
List list = new ArrayList();

Quadruple<Map<String, Object>, Integer, String, List> data = new Quadruple<>(map, number, string, list);

...

Map<String, Object> myMap = data.getFirst();
Integer myNumber = data.getSecond();
String myString = data.getThird();
List myList = data.getFourth();

0.2.0
