Constructor Detail
-
Tuple5
protected Tuple5(A a, B b, C c, D d, E e)
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 sub-type. Therefore, you have more flexibility with a static factory as part of your public API then with a public constructor.
