Description
| Interface Summary | |
|---|---|
| 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 Summary | |
|---|---|
| AbstractHashedMap | An abstract implementation of a hash-based map which provides numerous points for subclasses to override. |
| AbstractHashedMap.EntrySet | EntrySet implementation. |
| AbstractHashedMap.EntrySetIterator | EntrySet iterator. |
| AbstractHashedMap.HashEntry | HashEntry used to store the data. |
| AbstractHashedMap.HashIterator | Base Iterator |
| AbstractHashedMap.HashMapIterator | MapIterator implementation. |
| AbstractHashedMap.KeySet | KeySet implementation. |
| AbstractHashedMap.KeySetIterator | KeySet iterator. |
| AbstractHashedMap.Values | Values implementation. |
| AbstractHashedMap.ValuesIterator | Values iterator. |
| 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. |
| AbstractLinkedMap.EntrySetIterator | EntrySet iterator. |
| AbstractLinkedMap.KeySetIterator | KeySet iterator. |
| AbstractLinkedMap.LinkEntry | LinkEntry that stores the data. |
| AbstractLinkedMap.LinkIterator | Base Iterator that iterates in link order. |
| AbstractLinkedMap.LinkMapIterator | MapIterator implementation. |
| AbstractLinkedMap.ValuesIterator | Values iterator. |
| 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. |
| AbstractReferenceMap.ReferenceEntry | A MapEntry implementation for the map. |
| 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(). |
| IdentityMap.IdentityEntry | HashEntry |
| 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:
