All Implemented Interfaces:

Serializable, Iterable, Collection, List

Enclosing class:

Default

public static class Default.PairList<A,B>
extends AbstractList
implements Serializable

Pairs, implemented as a List. The Default.PairList implements hashCode() and equals() "properly" so they can be used as keys in hashtables and etc. They are implemented as mutable lists of fixed size 2. Note that the hashCode() implementation differs from pairs implemented as Map.Entrys; the parameterization is different as well.
