public class PairMapEntry<K,V> extends AbstractMapEntry<K,V>
PairMapEntry is the easiest implementation of a
Map.Entry ever: a pair! Basically saves coders the
drugery of writing an inner class at the expense of an import
statement.
Note that PairMapEntrys are mutable:
setValue(Object) is defined in this class.
Using null as a key or value will not cause this class
or AbstractMapEntry to fail, but be warned that
several Map implementations do not like
nulls in their internal structures.
