<center><h3>COMPATABILITY</h3></center>
|
|
<ul>
|
|
<li>ReferenceMap - No longer extends AbstractMap, only an issue if you previously cast to AbstractMap</li>
|
|
<li>FixedSizeSortedMap - No longer extends AbstractSortedMapDecorator, only an issue if you previously cast to AbstractSortedMapDecorator</li>
|
|
</ul>
|
|
|
|
<center><h3>NEW CLASSES</h3></center>
|
|
<ul>
|
|
<li>MultiKeyMap - A map that allows multiple keys to be used to map the value</li>
|
|
<li>SingletonMap - fully featured singleton Map implementation</li>
|
|
<li>TransformedPredicate - A predicate where the input object is transformed [26946]</li>
|
|
<li>ObjectGraphIterator - An iterator that can iterate over a graph of objects</li>
|
|
<li>MapBackedSet - Set created by decorating a map</li>
|
|
<li>ReferenceIdentityMap - Similar to ReferenceMap, but matching keys and values by identity [26503]</li>
|
|
<li>AbstractReferenceMap - New base class for reference maps [26503]</li>
|
|
<li>AbstractInputCheckedMapDecorator - New base class for map decorators that validate or alter input</li>
|
|
</ul>
|
|
|
|
<center><h3>ENHANCEMENTS</h3></center>
|
|
<ul>
|
|
<li>ReferenceMap - Changed to extend AbstractReferenceMap, thus gaining a mapIterator() and subclassability [26503]</li>
|
|
<li>Fast3Map - Add clone() method</li>
|
|
<li>MultiKey - Add getKey(index) and size() methods and make constructor public</li>
|
|
<li>MultiHashMap - Add five methods to improve the API</li>
|
|
<li>AbstractHashedMap,AbstractLinkedMap - Add methods to access entry methods when protected scope blocks</li>
|
|
<li>Functors - Add get methods to retrieve internal state [27515]</li>
|
|
<li>Functors - Add additional getInstance() methods for consistency [27856,27857]</li>
|
|
<li>CollectionUtils - get(Object,int) method now supports primitive arrays</li>
|
|
<li>CollectionUtils - cardinality() now works faster for Set and Bag instances [28629]</li>
|
|
<li>CollectionUtils - Add size(Object) method to find the size of various collection-like objects [27909]</li>
|
|
<li>SingletonIterator - make remove() functionality optional</li>
|
|
<li>AbstractLinkedList/NodeCachingLinkedList - added getValue() and setValue() to Node, and made everything use them</li>
|
|
<li>LRUMap - The addMapping() method now uses isFull() to determine whether it is full</li>
|
|
<li>LRUMap - Add boolean flag, scanUntilRemovable, giving the removeLRU() method more power [28887]</li>
|
|
</ul>
|
