Class Summary

AbstractIteratorDecorator<E>	Provides basic behaviour for decorating an iterator with extra functionality.
AbstractListIteratorDecorator<E>	Provides basic behaviour for decorating a list iterator with extra functionality.
AbstractMapIteratorDecorator<K,V>	Provides basic behaviour for decorating a map iterator with extra functionality.
AbstractOrderedMapIteratorDecorator<K,V>	Provides basic behaviour for decorating an ordered map iterator with extra functionality.
ArrayIterator<E>	Implements an Iterator over any array.
ArrayListIterator<E>	Implements a ListIterator over an array.
CollatingIterator<E>	Provides an ordered iteration over the elements contained in a collection of ordered Iterators.
EmptyIterator<E>	Provides an implementation of an empty iterator.
EmptyListIterator<E>	Provides an implementation of an empty list iterator.
EmptyMapIterator	Provides an implementation of an empty map iterator.
EmptyOrderedIterator<E>	Provides an implementation of an empty ordered iterator.
EmptyOrderedMapIterator	Provides an implementation of an empty ordered map iterator.
EntrySetMapIterator<K,V>	Implements a MapIterator using a Map entrySet.
EnumerationIterator<E>	Adapter to make Enumeration instances appear to be Iterator instances.
FilterIterator<E>	Decorates an iterator such that only elements matching a predicate filter are returned.
FilterListIterator<E>	A proxy ListIterator which takes a Predicate instance to filter out objects from an underlying ListIterator instance.
IteratorChain<E>	An IteratorChain is an Iterator that wraps a number of Iterators.
IteratorEnumeration<E>	Adapter to make an Iterator instance appear to be an Enumeration instance.
ListIteratorWrapper<E>	As the wrapped Iterator is traversed, ListIteratorWrapper builds a LinkedList of its values, permitting all required operations of ListIterator.
LoopingIterator<E>	An Iterator that restarts when it reaches the end.
ObjectArrayIterator<E>	An Iterator over an array of objects.
ObjectArrayListIterator<E>	Implements a ListIterator over an array of objects.
ObjectGraphIterator	An Iterator that can traverse multiple iterators down an object graph.
SingletonIterator<E>	SingletonIterator is an Iterator over a single object instance.
SingletonListIterator<E>	SingletonIterator is an ListIterator over a single object instance.
TransformIterator<I,O>	Decorates an iterator such that each element returned is transformed.
UniqueFilterIterator<E>	A FilterIterator which only returns "unique" Objects.
UnmodifiableIterator<E>	Decorates an iterator such that it cannot be modified.
UnmodifiableListIterator<E>	Decorates a list iterator such that it cannot be modified.
UnmodifiableMapIterator<K,V>	Decorates a map iterator such that it cannot be modified.
UnmodifiableOrderedMapIterator<K,V>	Decorates an ordered map iterator such that it cannot be modified.

Package org.apache.commons.collections.iterators Description

This package contains implementations of the Iterator interface.

You may also consider using IteratorUtils, which is a single class that uses static methods to construct instances of the classes in this package.
