Description

Class Summary
AbstractLinkedList | An abstract implementation of a linked list which provides numerous points for subclasses to override.
AbstractLinkedList.LinkedListIterator | A list iterator over the linked list.
AbstractLinkedList.LinkedSubList | The sublist implementation for AbstractLinkedList.
AbstractLinkedList.LinkedSubListIterator | A list iterator over the linked sub list.
AbstractLinkedList.Node | A node within the linked list.
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.
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 it's 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
- SetUnique - a list that avoids duplicate entries like a Set
