| Unmodifiable | Marker interface for collections, maps and iterators that are unmodifiable. |
| Classes | |
|---|---|
| ArrayStack | An implementation of the Stack API that is based on an
ArrayList instead of a Vector, so it is not
synchronized to protect against multi-threaded access. |
| BagUtils | Provides utility methods and decorators for Bag and SortedBag instances. |
| BeanMap | An implementation of Map for JavaBeans which uses introspection to get and put properties in the bean. |
| BeanMap.MyMapEntry | Map entry used by BeanMap . |
| BinaryHeap | Binary heap implementation of PriorityQueue. |
| BoundedFifoBuffer | The BoundedFifoBuffer is a very efficient implementation of Buffer that does not alter the size of the buffer at runtime. |
| BufferUtils | Provides utility methods and decorators for Buffer instances. |
| ClosureUtils | ClosureUtils provides reference implementations and utilities
for the Closure functor interface. |
| CollectionUtils | Provides utility methods and decorators for Collection instances. |
| ComparatorUtils | Provides convenient static utility methods for Comparator
objects. |
| CursorableLinkedList | A doubly-linked list implementation of the List interface, supporting a ListIterator that allows concurrent modifications to the underlying list. |
| CursorableLinkedList.Cursor | No description provided. |
| DefaultMapBag | A skeletal implementation of the Bag interface to minimize the effort required for target implementations. |
| DefaultMapEntry | A default implementation of Map.Entry |
| DoubleOrderedMap | Red-Black tree-based implementation of Map. |
| EnumerationUtils | Provides utility methods for Enumeration instances. |
| ExtendedProperties | This class extends normal Java properties by adding the possibility to use the same key many times concatenating the value strings instead of overwriting them. |

for the Factory functor interface. |
| FastArrayList | A customized implementation of |
| FastHashMap | A customized implementation of |

| IteratorUtils | Provides static utility methods and decorators for Iterator instances. |
| ListUtils | Provides utility methods and decorators for List instances. |
| LRUMap | An implementation of a Map which has a maximum size and uses a Least Recently Used algorithm to remove items from the Map when the maximum size is reached and new items are added. |
| MapUtils | Provides utility methods and decorators for Map and SortedMap instances. |
| MultiHashMap | MultiHashMap is the default implementation of the
MultiMap interface. |
| PredicateUtils | PredicateUtils provides reference implementations and utilities
for the Predicate functor interface. |
| ProxyMap | This |
| ReferenceMap | Hash-based Map implementation that allows mappings to be removed by the garbage collector. |
| SequencedHashMap | A map of objects whose mapping entries are sequenced based on the order in which they were added. |
| SetUtils | Provides utility methods and decorators for Set and SortedSet instances. |
| StaticBucketMap | A StaticBucketMap is an efficient, thread-safe implementation of
java.util.Map that performs well in in a highly
thread-contentious environment. |
| SynchronizedPriorityQueue | A thread safe version of the PriorityQueue. |

utilities for the Transformer functor interface. |
