- org.organicdesign.fp.tuple.Tuple12<A,B,C,D,E,F,G,H,I,J,K,L>

All Implemented Interfaces:

Serializable
```
public class Tuple12<A,B,C,D,E,F,G,H,I,J,K,L>
extends Object
implements Serializable
```
Holds 12 items of potentially different types. Designed to let you easily create immutable subclasses (to give your data structures meaningful names) with correct equals(), hashCode(), and toString() methods.

Constructor is protected (not public) for easy inheritance. Josh Bloch's "Item 1" says public static factory methods are better than constructors because they have names, they can return an existing object instead of a new one, and they can return a subtype. Therefore, you have more flexibility with a static factory as part of your public API then with a public constructor.
