ClassDescriptionGet<K,
V> The "read" subset of theMapinterface.IterableGet<K,V> The "read" subset of theMapinterface.IterableMap<K,V> Defines a map that can be iterated directly without needing to create an entry set.IterableSortedMap<K,V> MapIterator<K,V> Defines an iterator that operates over aMap.Defines an iterator that operates over an ordered container.OrderedMap<K,V> Defines a map that maintains order and allows both forward and backward iteration through that order.OrderedMapIterator<K,V> Defines an iterator that operates over an orderedMap.Put<K,V> The "write" subset of theMapinterface.Trie<K,V> Defines the interface for a prefix tree, an ordered tree data structure.A collection ofTrieutilities.Marker interface for collections, maps and iterators that are unmodifiable.
