## Interface KeyValue<K,V>

- Type Parameters:
    `K` - the type of the key
    `V` - the type of the value
  All Known Implementing Classes:
    AbstractDualBidiMap.MapEntry, AbstractHashedMap.HashEntry, AbstractKeyValue, AbstractLinkedMap.LinkEntry, AbstractMapEntry, AbstractMapEntryDecorator, AbstractReferenceMap.ReferenceEntry, DefaultKeyValue, DefaultMapEntry, SingletonMap, TiedMapEntry, UnmodifiableMapEntry

      public interface KeyValue<K,V>

  Defines a simple key value pair.

  A Map Entry has considerable additional semantics over and above a simple key-value pair. This interface defines the minimum key value, with just the two get methods.

  Since:
    3.0
