Class Summary

Class	Description
AbstractLinkedList<E>	An abstract implementation of a linked list which provides numerous points for subclasses to override.
AbstractListDecorator<E>	Decorates another List to provide additional behaviour.
AbstractSerializableListDecorator<E>	Serializable subclass of AbstractListDecorator.
CursorableLinkedList<E>	A List implementation with a ListIterator that allows concurrent modifications to the underlying list.
CursorableLinkedList.Cursor<E>	An extended ListIterator that allows concurrent changes to the underlying list.
FixedSizeList<E>	Decorates another List to fix the size preventing add/remove.
GrowthList<E>	Decorates another List to make it seamlessly grow when indices larger than the list size are used on add and set, avoiding most IndexOutOfBoundsExceptions.
LazyList<E>	Decorates another List to create objects in the list on demand.
NodeCachingLinkedList<E>	A List implementation that stores a cache of internal Node objects in an effort to reduce wasteful object creation.
PredicatedList<E>	Decorates another List to validate that all additions match a specified predicate.
SetUniqueList<E>	Decorates a List to ensure that no duplicates are present much like a Set.
TransformedList<E>	Decorates another List to transform objects that are added.
TreeList<E>	A List implementation that is optimised for fast insertions and removals at any index in the list.
UnmodifiableList<E>	Decorates another List to ensure it can't be altered.

Package org.apache.commons.collections4.list Description

This package contains implementations of the List interface.

The following implementations are provided in the package:

• TreeList - a list that is optimised for insertions and removals at any index in the list
• CursorableLinkedList - a list that can be modified while the listIterator (cursor) is being used
• NodeCachingLinkedList - a linked list that caches the storage nodes for a performance gain

The following decorators are provided in the package:

• Unmodifiable - ensures the collection cannot be altered
• Predicated - ensures that only elements that are valid according to a predicate can be added
• Transformed - transforms each element added
• FixedSize - ensures that the size of the list cannot change
• Lazy - creates objects in the list on demand
• Growth - grows the list instead of erroring when set/add used with index beyond the list size
• SetUnique - a list that avoids duplicate entries like a Set
