    Subinterfaces of OrderedMap in org.apache.commons.collections
    Modifier and Type | Interface and Description
    --- | ---
    `interface` | `OrderedBidiMap` Defines a map that allows bidirectional lookup between key and values and retains and provides access to an ordering.
    `interface` | `SortedBidiMap` Defines a map that allows bidirectional lookup between key and values and retains both keys and values in sorted order.

  - ### Uses of OrderedMap in org.apache.commons.collections.bidimap

    Classes in org.apache.commons.collections.bidimap that implement OrderedMap
    Modifier and Type | Class and Description
    --- | ---
    `class` | `AbstractOrderedBidiMapDecorator` Provides a base decorator that enables additional functionality to be added to an OrderedBidiMap via decoration.
    `class` | `AbstractSortedBidiMapDecorator` Provides a base decorator that enables additional functionality to be added to a SortedBidiMap via decoration.
    `class` | `DualTreeBidiMap` Implementation of `BidiMap` that uses two `TreeMap` instances.
    `class` | `TreeBidiMap` Red-Black tree-based implementation of BidiMap where all objects added implement the `Comparable` interface.
    `class` | `UnmodifiableOrderedBidiMap` Decorates another `OrderedBidiMap` to ensure it can't be altered.
    `class` | `UnmodifiableSortedBidiMap` Decorates another `SortedBidiMap` to ensure it can't be altered.

  - ### Uses of OrderedMap in org.apache.commons.collections.map

    Classes in org.apache.commons.collections.map that implement OrderedMap
    Modifier and Type | Class and Description
    --- | ---
    `class` | `AbstractLinkedMap` An abstract implementation of a hash-based map that links entries to create an ordered map and which provides numerous points for subclasses to override.
    `class` | `AbstractOrderedMapDecorator` Provides a base decorator that enables additional functionality to be added to an OrderedMap via decoration.
    `class` | `LinkedMap` A `Map` implementation that maintains the order of the entries.
    `class` | `ListOrderedMap` Decorates a `Map` to ensure that the order of addition is retained using a `List` to maintain order.
    `class` | `LRUMap` A `Map` implementation with a fixed maximum size which removes the least recently used entry if an entry is added when full.
    `class` | `SingletonMap` A `Map` implementation that holds a single item and is fixed size.
    `class` | `UnmodifiableOrderedMap` Decorates another `OrderedMap` to ensure it can't be altered.
