Description

Interface Summary

Bag An unordered (as opposed to unsorted) Collection that allows multiple instances of the same object to be added.

MultiMap A map (similar to, but not a java.util.Map) which allows multiple values for the same key.

Operation An operation, which executes on a specified object.

Partition A Partition is a set in which every element is assigned to an equivalence class, here referred to as a "buckets" (for both brevity and unambiguity with regard to java classes).

Predicate A predicate, which evaluates a specified object and returns either true or false.

SortedBag A sorted Bag, see java.util.SortedSet for the sorting semantics and behavior.

SortedMultiMap A sorted MultiMap, see java.util.SortedMap for the sorting semantics and behavior.

Transformer An object which transforms a specified object and returns the result.

Class Summary

AllTests Test suite for all tests in this package.

ClassMap A java.util.HashMap where the keys are java.lang.Class objects.

CollectionChain A java.util.Collection which is a view of a list of other Collections chained together.

DefaultMapBag A java.util.Map based implementation of the Bag interface.

DefaultMultiMap A java.util.Map based implementation of the MultiMap interface.

DefaultPartition A default Partition implementation.

FilteredCollection A view of a java.util.Collection filtered by a Predicate.

FilteredList A view of a java.util.List filtered by a Predicate.

FilteredListIterator A java.util.ListIterator over a java.util.List filtered by a Predicate.

IdentityHashSet An implementation of the java.util.Set interface backed by an java.util.IdentityHashMap.

IteratorUtils This class contains static methods to perform some common tasks with iterators.

IteratorUtils.EmptyIterator

IteratorUtils.EmptyListIterator

PredicateUtils Useful PredicateUtils.TruePredicate creational methods and constant values.

PredicateUtils.AndPredicate

PredicateUtils.CollectionAndPredicate

PredicateUtils.CollectionOrPredicate

PredicateUtils.FalsePredicate

Package us.rconner.util.collection Description

Contains mutable primitive wrappers. These objects should NOT be used as keys in a hash table, but they work well for other situations where being both mutable and an Object is required.
