Thanks to Matt Bishop. +This version uses the generics features of Java 5 and is not compatible with +earlier JDK versions. +The process of generifying an API is complex. +For commons-collections, we have chosen to break the API in various ways. +The aim behind this is to provide an API design that better suits generics. +We have also removed all deprecated classes and fixed oddities in the previous +API that we couldn't fix due to backwards compatibility restrictions. + +As such, this release can not be considered to be a simple, drop-in, replacement +for commons-collections. To help with the migration to this new version, the +package has changed to "org.apache.commons.collections4", thus it is possible +to have both commons-collections versions in the classpath. + +These release notes will try to guide you in the process of upgrading, however you +should remember that this is a new API based on the original, so some concepts +have changed. + +Compatibility +------------- + + o Java 5 or later is required. + o This release is not source or binary compatible with previous releases of + Commons Collections. This includes releases from the 3.x branch as well as + preceding alpha releases for 4.0 (see details of changes below). + o some unit tests are disabled when executed with an IBM JDK 6 due to a faulty + java.util.TreeMap implementation. + + +Major changes since 3.2.1 +------------------------- + + o Use of generics and other language features introduced in Java 5 (varargs, Iterable) + o Removed deprecated classes / methods and features which are now supported by the JDK + o Replaced Buffer interface with java.util.Queue + o Added concept of split maps with respective interfaces Put / Get (see also package splitmap) + o Added new Trie interface together with an implementation of a Patricia Trie + + +Changes since 4.0-alpha1 +------------------------ + + o [COLLECTIONS-502] Resolved generic parameter inconsistency for various static fields, e.g. BagUtils.EMPTY_BAG, + TruePredicate.INSTANCE and many others. All accessible static fields use raw types so that + they can be used directly without explicit casting. To avoid compiler warnings about unchecked + conversion and/or rawtypes use the corresponding factory methods, e.g. BagUtils.emptyBag(). + o [COLLECTIONS-501] Renamed methods "V MultiKeyMap#remove(Object, Object, ...)" to + "V MultiKeyMap#removeMultiKey(Object, Object, ...)" to avoid future conflicts + with a default method of the Map interface in Java 8. + o [COLLECTIONS-500] Renamed "V MultiMap#remove(K, V)" to "boolean MultiMap#removeMapping(K, V)" + to avoid future conflicts with a default method of the Map interface in Java 8. + o [COLLECTIONS-499] Refactored the test framework for Bag implementations to extend from + "AbstractCollectionTest" by decorating the concrete Bag instance with + a CollectionBag or CollectionSortedBag. + o [COLLECTIONS-498] "CollectionBag" will now also respect the contract of the decorated bag in case + a null argument is provided to either removeAll or retainAll. + o [COLLECTIONS-497] Added bag decorator "CollectionSortedBag" which decorates a SortedBag to make it + comply with the Collection contract. + o [COLLECTIONS-496] "UnmodifiableBoundedCollection" does now also implement the marker interface "Unmodifiable" + similar as all other unmodifiable decorators. + o [COLLECTIONS-495] "UnmodifiableTrie#unmodifiableTrie(Trie)" will not decorate again an already unmodifiable Trie. + Also the return type has been changed to "Trie" to be consistent with other Unmodifiable decorators. + o [COLLECTIONS-494] Moved "Equator" interface to base package for consistency. Thanks to Emmanuel Bourg. + o [COLLECTIONS-488] Added "CollectionsUtils#matchesAll(Iterable, Predicate)" to test if all elements + of a collection match a given predicate.

Thanks to Hollis Waite. + o [COLLECTIONS-481] No collision detection/resolution was performed when calling "CompositeSet#addComposited(...)" + with more than one Set as argument. Additionally use varargs parameters instead of arrays + in CompositeSet and CompositeCollection constructor and addComposited method. Thanks to Hollis Waite. + o [COLLECTIONS-480] Narrow return type of "BidiMap#values()" to Set as the values are required to be unique. Thanks to Hollis Waite. + o [COLLECTIONS-468] Renamed CompliantBag to CollectionBag. + o [COLLECTIONS-475] Fixed conversion of timeout parameters in "PassiveExpiringMap". + + +Removed classes +--------------- + + o [COLLECTIONS-458] Removed unused class "AbstractUntypedCollectionDecorator<E, D>" + o [COLLECTIONS-432] Removed "Buffer" interface and all its implementations and related classes. + Replaced by "java.util.Queue", see also section [New classes] + + - PriorityBuffer: use either java.util.PriorityQueue or java.util.concurrent.PriorityBlockingQueue + - SynchronizedBuffer: use the corresponding *BlockingQueue classes in java.util.concurrent + - BoundedBuffer: use either ArrayBlockingBuffer(capacity) or LinkedBlockingBuffer(capacity) in java.util.concurrent + - UnboundedFifoBuffer: use either java.util.LinkedList or java.util.concurrent.LinkedBlockingBuffer + + o [COLLECTIONS-351] Removed features now supported by the JDK or other Apache Commons libraries -For complete information on Apache Commons Collections, including instructions on how to submit bug reports, + - FastArrayList: use java.util.concurrent.CopyOnWriteArrayList + - FastHashMap: use java.util.concurrent.ConcurrentHashMap, but beware of null keys and values + - FastTreeSet: no direct replacement, use ConcurrentHashMap or a synchronized TreeMap + - IdentityMap: use java.util.IdentityHashMap + - ExtendedProperties: use commons-configuration + - Synchronized[List,Set,SortedSet]: use java.util.Collections.synchronized*() + - Typed* decorators: use generics for type safety, or java.util.Collections.checked*() + - [List,Set,Map]Utils.EMPTY_*: use the corresponding fields in java.util.Collections + + o [COLLECTIONS-229] Removed deprecated collection classes and methods + + +New classes +----------- + + o [COLLECTIONS-497] CollectionSortedBag - decorates a SortedBag to make it comply with the Collection contract. + o [COLLECTIONS-468] CollectionBag - decorates another Bag to make it comply with the Collection contract. + o [COLLECTIONS-463] PushbackIterator - supports pushback of elements during iteration. Thanks to Andy Seaborne, Claude Warren. + o [COLLECTIONS-462] PeekingIterator - supports one-element lookahead during iteration.
