| libgoogle-collections-java | suite of collections and related goodies for Java 5.0 | Mehr ... |
This library is a natural extension of the Java Collections Framework. The
major new types are:
* BiMap. A Map that guarantees unique values, and supports an inverse view.
* Multiset. A Collection that may contain duplicate values like a List, yet
has order-independent equality like a Set. Often used to represent a
histogram.
* Multimap. Similar to Map, but may contain duplicate keys. Has subtypes
SetMultimap and ListMultimap providing more specific behavior.
.
There are also more than a dozen collection implementations, mostly of the
interfaces above, but not all. ReferenceMap, for example, is a ConcurrentMap
implementation which easily handles any combination of strong, soft or weak
keys with strong, soft or weak values. Static utility classes include:
* Comparators. Natural order, compound, null-friendly, ad-hoc, ...
* Iterators and Iterables. Element-based equality, cycle, concat, partition,
filter with predicate, transform with function ...
* Lists, Sets and Maps. A plethora of convenient factory methods and much
more.
* PrimitiveArrays: "boxing"/"unboxing" of primitive arrays
.
And there's more:
* Immutable collections
* Forwarding collections
* Constrained collections
* Implementation helpers like AbstractIterator |
