PairMapEntry<K,V> (JUtil documentation)

Class PairMapEntry<K,V>

public class PairMapEntry<K,V> extends AbstractMapEntry<K,V>

PairMapEntry is the easiest implementation of a java.util.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: PairMapEntry 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 java.util.Map implementations do not like nulls in their internal structures.
