Interface | Description |
---|---|
CompositeMap.MapMutator |
This interface allows definition for all of the indeterminate
mutators in a CompositeMap, as well as providing a hook for
callbacks on key collisions.
|
Class | Description |
---|---|
AbstractHashedMap |
An abstract implementation of a hash-based map which provides numerous points for
subclasses to override.
|
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.
|
AbstractMapDecorator |
Provides a base decorator that enables additional functionality to be added
to a Map via decoration.
|
AbstractOrderedMapDecorator |
Provides a base decorator that enables additional functionality to be added
to an OrderedMap via decoration.
|
AbstractReferenceMap |
An abstract implementation of a hash-based map that allows the entries to
be removed by the garbage collector.
|
AbstractSortedMapDecorator |
Provides a base decorator that enables additional functionality to be added
to a Map via decoration.
|
CaseInsensitiveMap |
A case-insensitive
Map . |
CompositeMap |
Decorates a map of other maps to provide a single unified view.
|
DefaultedMap |
Decorates another
Map returning a default value if the map
does not contain the requested key. |
FixedSizeMap |
Decorates another
Map to fix the size, preventing add/remove. |
FixedSizeSortedMap |
Decorates another
SortedMap to fix the size blocking add/remove. |
Flat3Map |
A
Map implementation that stores data in simple fields until
the size is greater than 3. |
HashedMap |
A
Map implementation that is a general purpose alternative
to HashMap . |
IdentityMap |
A
Map implementation that matches keys and values based
on == not equals() . |
LazyMap |
Decorates another
Map to create objects in the map on demand. |
LazySortedMap |
Decorates another
SortedMap to create objects in the map on demand. |
LinkedMap |
A
Map implementation that maintains the order of the entries. |
ListOrderedMap |
Decorates a
Map to ensure that the order of addition is retained
using a List to maintain order. |
LRUMap |
A
Map implementation with a fixed maximum size which removes
the least recently used entry if an entry is added when full. |
MultiKeyMap |
A
Map implementation that uses multiple keys to map the value. |
MultiValueMap |
A MultiValueMap decorates another map, allowing it to have
more than one value for a key.
|
PredicatedMap |
Decorates another
Map to validate that additions
match a specified predicate. |
PredicatedSortedMap |
Decorates another
SortedMap to validate that additions
match a specified predicate. |
ReferenceIdentityMap |
A
Map implementation that allows mappings to be
removed by the garbage collector and matches keys and values based
on == not equals() . |
ReferenceMap |
A
Map implementation that allows mappings to be
removed by the garbage collector. |
SingletonMap |
A
Map implementation that holds a single item and is fixed size. |
StaticBucketMap |
A StaticBucketMap is an efficient, thread-safe implementation of
java.util.Map that performs well in in a highly
thread-contentious environment. |
TransformedMap |
Decorates another
Map to transform objects that are added. |
TransformedSortedMap |
Decorates another
SortedMap to transform objects that are added. |
TypedMap |
Decorates another
Map to validate that elements added
are of a specific type. |
TypedSortedMap |
Decorates another
SortedMap to validate that elements added
are of a specific type. |
UnmodifiableEntrySet |
Decorates a map entry
Set to ensure it can't be altered. |
UnmodifiableMap |
Decorates another
Map to ensure it can't be altered. |
UnmodifiableOrderedMap |
Decorates another
OrderedMap to ensure it can't be altered. |
UnmodifiableSortedMap |
Decorates another
SortedMap to ensure it can't be altered. |
This package contains implementations of the
Map
,
IterableMap
,
OrderedMap
and
SortedMap
interfaces.
A Map provides a lookup from a key to a value.
A number of implementations also support the new MapIterator interface that enables
simple iteration of map keys and values.
The following implementations are provided:
The following decorators are provided:
