    Subinterfaces of OrderedMap in org.apache.commons.collections4
    Modifier and Type | Interface and Description
    --- | ---
    `interface` | `IterableSortedMap<K,V>` `SortedMap` + `OrderedMap`.
    `interface` | `OrderedBidiMap<K,V>` Defines a map that allows bidirectional lookup between key and values and retains and provides access to an ordering.
    `interface` | `SortedBidiMap<K,V>` Defines a map that allows bidirectional lookup between key and values and retains both keys and values in sorted order.
    `interface` | `Trie<K,V>` Defines the interface for a prefix tree, an ordered tree data structure.

    Methods in org.apache.commons.collections4 that return OrderedMap
    Modifier and Type | Method and Description
    --- | ---
    `static <K,V> OrderedMap<K,V>` | MapUtils.`orderedMap(Map<K,V> map)` Returns a map that maintains the order of keys that are added backed by the given map.

    `class` | `LRUMap<K,V>` A `Map` implementation with a fixed maximum size which removes the least recently used entry if an entry is added when full.
    `class` | `SingletonMap<K,V>` A `Map` implementation that holds a single item and is fixed size.
    `class` | `UnmodifiableOrderedMap<K,V>` Decorates another `OrderedMap` to ensure it can't be altered.
    `class` | `UnmodifiableSortedMap<K,V>` Decorates another `SortedMap` to ensure it can't be altered.
