• Interface Summary 

  Interface	Description
  Bag<E>	Defines a collection that counts the number of times an object appears in the collection.
  BidiMap<K,V>	Defines a map that allows bidirectional lookup between key and values.
  BoundedCollection<E>	Defines a collection that is bounded in size.
  BoundedMap<K,V>	Defines a map that is bounded in size.
  Buffer<E>	Defines a collection that allows objects to be removed in some well-defined order.
  Closure<T>	Defines a functor interface implemented by classes that do something.
  Factory<T>	Defines a functor interface implemented by classes that create objects.
  Get<K,V>	The "read" subset of the Map interface.
  IterableGet<K,V>	The "read" subset of the Map interface.
  IterableMap<K,V>	Defines a map that can be iterated directly without needing to create an entry set.
  IterableSortedMap<K,V>	SortedMap + OrderedMap.
  KeyValue<K,V>	Defines a simple key value pair.
  MapIterator<K,V>	Defines an iterator that operates over a Map.
  MultiMap<K,V>	Defines a map that holds a collection of values against each key.
  OrderedBidiMap<K,V>	Defines a map that allows bidirectional lookup between key and values and retains and provides access to an ordering.
  OrderedIterator<E>	Defines an iterator that operates over an ordered container.
  OrderedMap<K,V>	Defines a map that maintains order and allows both forward and backward iteration through that order.
  OrderedMapIterator<K,V>	Defines an iterator that operates over an ordered Map.
  Predicate<T>	Defines a functor interface implemented by classes that perform a predicate test on an object.
  Put<K,V>	The "write" subset of the Map interface.
  ResettableIterator<E>	Defines an iterator that can be reset back to an initial state.
  ResettableListIterator<E>	Defines a list iterator that can be reset back to an initial state.
  SortedBag<E>	Defines a type of Bag that maintains a sorted order among its unique representative members.
  SortedBidiMap<K,V>	Defines a map that allows bidirectional lookup between key and values and retains both keys and values in sorted order.
  Transformer<I,O>	Defines a functor interface implemented by classes that transform one object into another.
  Trie<K,V>	Defines the interface for a prefix tree, an ordered tree data structure.
  Trie.Cursor<K,V>	A Trie.Cursor can be used to traverse a Trie, visit each node step by step and make Trie.Cursor.Decisions on each step how to continue with traversing the Trie.
  Unmodifiable	Marker interface for collections, maps and iterators that are unmodifiable.

• Class Summary 

  Class	Description
  ArrayStack<E>	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.
  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.
  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.
  IteratorUtils	Provides static utility methods and decorators for Iterator instances.
  ListUtils	Provides utility methods and decorators for List instances.
  MapUtils	Provides utility methods and decorators for Map and SortedMap instances.
  PredicateUtils	PredicateUtils provides reference implementations and utilities for the Predicate functor interface.
  SetUtils	Provides utility methods and decorators for Set and SortedSet instances.
  SplitMapUtils	Utilities for working with "split maps:" objects that implement Put and/or Get but not Map.
  TransformerUtils	TransformerUtils provides reference implementations and utilities for the Transformer functor interface.
  TrieUtils	A collection of Trie utilities.

• Enum Summary 

  Enum	Description
  Trie.Cursor.Decision	The Trie.Cursor.Decision tells the Trie.Cursor what to do on each step while traversing the Trie.

• Exception Summary 

  Exception	Description
  BufferOverflowException	The BufferOverflowException is used when the buffer's capacity has been exceeded.
  BufferUnderflowException	The BufferUnderflowException is used when the buffer is already empty.
  FunctorException	Runtime exception thrown from functors.
