Class Triple<A,B,C>

Object

com.net2plan.utils.Triple<A,B,C>

public class Triple<A,B,C>
extends Object

A triple consisting of three 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";

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

...

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