| Bag
Defines a collection that counts the number of times an object appears in
the collection.
|
| BeanMap
Deprecated.
Identical class now available in commons-beanutils (full jar version).
This version is due to be removed in collections v4.0.
|
| BidiMap
Defines a map that allows bidirectional lookup between key and values.
|
| BoundedCollection
Defines a collection that is bounded in size.
|
| Buffer
Defines a collection that allows objects to be removed in some well-defined order.
|
| Closure
Defines a functor interface implemented by classes that do something.
|
| CursorableLinkedList.Cursor
Deprecated.
|
| DefaultMapBag
Deprecated.
Moved to bag subpackage as AbstractMapBag. Due to be removed in v4.0.
|
| 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.
