Class Summary

Class	Description
AbstractLinkedList	An abstract implementation of a linked list which provides numerous points for subclasses to override.
AbstractListDecorator	Decorates another List to provide additional behaviour.
AbstractSerializableListDecorator	Serializable subclass of AbstractListDecorator.
CursorableLinkedList	A List implementation with a ListIterator that allows concurrent modifications to the underlying list.
CursorableLinkedList.Cursor	An extended ListIterator that allows concurrent changes to the underlying list.
FixedSizeList	Decorates another List to fix the size preventing add/remove.
GrowthList	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	Decorates another List to create objects in the list on demand.
NodeCachingLinkedList	A List implementation that stores a cache of internal Node objects in an effort to reduce wasteful object creation.
PredicatedList	Decorates another List to validate that all additions match a specified predicate.
SetUniqueList	Decorates a List to ensure that no duplicates are present much like a Set.
SynchronizedList	Decorates another List to synchronize its behaviour for a multi-threaded environment.
TransformedList	Decorates another List to transform objects that are added.
TreeList	A List implementation that is optimised for fast insertions and removals at any index in the list.
TypedList	Decorates another List to validate that elements added are of a specific type.
UnmodifiableList	Decorates another List to ensure it can't be altered.

Package org.apache.commons.collections.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:

• Synchronized - synchronizes method access for multi-threaded environments
• Unmodifiable - ensures the collection cannot be altered
• Predicated - ensures that only elements that are valid according to a predicate can be added
• Typed - ensures that only elements that are of a specific type 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
