| Modifier and Type | Interface and Description |
|---|---|
interface |
BidiMap
Defines a map that allows bidirectional lookup between key and values.
|
interface |
OrderedBidiMap
Defines a map that allows bidirectional lookup between key and values
and retains and provides access to an ordering.
|
interface |
OrderedMap
Defines a map that maintains order and allows both forward and backward
iteration through that order.
|
interface |
SortedBidiMap
Defines a map that allows bidirectional lookup between key and values
and retains both keys and values in sorted order.

to a BidiMap via decoration.
|
class |
AbstractDualBidiMap
Abstract
BidiMap implemented using two maps. |
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 |
DualHashBidiMap
Implementation of
BidiMap that uses two HashMap instances. |
class |
DualTreeBidiMap

BidiMap that uses two TreeMap instances. |
class |
TreeBidiMap
Red-Black tree-based implementation of BidiMap where all objects added
implement the
Comparable interface. |

SortedBidiMap to ensure it can't be altered. |
| Modifier and Type | Class and Description |
|---|---|
class |
AbstractHashedMap
An abstract implementation of a hash-based map which provides numerous points for
subclasses to override.
|
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 |
AbstractReferenceMap
An abstract implementation of a hash-based map that allows the entries to
be removed by the garbage collector.
|
class |
CaseInsensitiveMap
A case-insensitive
Map. |
class |
Flat3Map
A
Map implementation that stores data in simple fields until
the size is greater than 3. |
class |
HashedMap
A
Map implementation that is a general purpose alternative
to HashMap. |
class |
IdentityMap
A
Map implementation that matches keys and values based
on == not equals(). |
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 |
MultiKeyMap
A
Map implementation that uses multiple keys to map the value. |
class |
ReferenceIdentityMap
A
Map implementation that allows mappings to be
removed by the garbage collector and matches keys and values based
on == not equals(). |
class |
ReferenceMap
A
Map implementation that allows mappings to be
removed by the garbage collector. |
class |
SingletonMap
A
Map implementation that holds a single item and is fixed size. |
class |
UnmodifiableMap
Decorates another
Map to ensure it can't be altered. |
class |
UnmodifiableOrderedMap
Decorates another
OrderedMap to ensure it can't be altered. |
