Store Object in key/value format

Question

Is there a way I can store my objects as a value in a key/value list? I tried using a HashMap but it kept returning an NULL, I'm assuming its because its not storing the object itself.

This should work:
import java.util.HashMap;
class A {
    public var num : Number;
class B {
    public var text : String;
    public override function toString():String { text }
var a1 = A{ num: 1 };
var a2 = A{ num: 2 };
var b1 = B{ text: "One" };
var b2 = B{ text: "Two" };
var hashMap = new HashMap();
hashMap.put(a1, b1);
hashMap.put(a2, b2);
var value = hashMap.get(a1);
println(value);
