| Interface | Description |
|---|---|

| MapIterator |
Defines an iterator that operates over a
Map. |
| MultiMap |
Defines a map that holds a collection of values against each key.

Defines a map that allows bidirectional lookup between key and values
and retains and provides access to an ordering.
|
| OrderedIterator |
Defines an iterator that operates over an ordered collection.
|
| OrderedMap |
Defines a map that maintains order and allows both forward and backward
iteration through that order.
|
| OrderedMapIterator |
Defines an iterator that operates over an ordered
Map. |

|
| SortedBag |
Defines a type of
Bag that maintains a sorted order among
its unique representative members. |

and retains both keys and values in sorted order.
|
| Transformer |
Defines a functor interface implemented by classes that transform one
object into another.
|
| Unmodifiable |
Marker interface for collections, maps and iterators that are unmodifiable.
|
| Class | Description |
|---|---|
| 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. |

Provides utility methods and decorators for
Collection instances. |
| ComparatorUtils |
Provides convenient static utility methods for
Comparator
objects. |
| CursorableLinkedList | Deprecated
Use new version in list subpackage, which has been rewritten
and now returns the cursor from the listIterator method.
|
| DefaultMapBag | Deprecated
Moved to bag subpackage as AbstractMapBag.
|

Use the version in the keyvalue subpackage.
|
| DoubleOrderedMap | Deprecated
Replaced by TreeBidiMap in bidimap subpackage.
|
| 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.
|
| FactoryUtils |
FactoryUtils provides reference implementations and utilities
for the Factory functor interface. |
| FastArrayList |
A customized implementation of
java.util.ArrayList designed
to operate in a multithreaded environment where the large majority of
method calls are read-only, instead of structural changes. |
| FastHashMap |
A customized implementation of
java.util.HashMap designed
to operate in a multithreaded environment where the large majority of
method calls are read-only, instead of structural changes. |
| FastTreeMap |
A customized implementation of
java.util.TreeMap designed
to operate in a multithreaded environment where the large majority of
method calls are read-only, instead of structural changes. |
