Package org.apache.commons.collections4.list
package org.apache.commons.collections4.list
Implements the
List interface.
The following implementations are provided in the package:
- TreeList - a list that is optimized 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 erring when set/add used with index beyond the list size
- SetUnique - a list that avoids duplicate entries like a Set
