Interface Summary

Interface	Description
Cache<K,V>	Represents a cache.
Cleanups.Cleanup	The interface to implement for each cleanup.
Converter<F,T>	A converter used to convert a value to another.
FilterMap.Filter<V>	Filters the given value (to evaluate when the value is retrieved).

Class Summary

Class	Description
ArraysX	Utilities for handling arrays.
CacheMap<K,V>	The cache map.
CacheMap.Value<V>	The class to hold key/value.
Checksums	Checksum relevant utilities.
Cleanups	Utilities to clean up resources when the application is stopping.
CollectionsX	The collection related utilities.
CollectionsX.ArrayCollection<E>	An readonly collection on top of an array.
CollectionsX.ArrayEnumeration<E>	An enumeration on top of an array.
CollectionsX.ArrayIterator<E>	An iterator on top of an array.
CollectionsX.ArrayList<E>	An readonly list on top of an array.
CollectionsX.ArrayListIterator<E>
CollectionsX.CollectionEnumeration<E>	An enumeration on top of a collection or iterator.
CollectionsX.EnumerationIterator<E>	An iterator that iterates thru an Enumeration.
CollectionsX.OneCollection<E>	A collection that contains only one element.
CollectionsX.OneEnumeration<E>	An enumeration that enumerates one element.
CollectionsX.OneIterator<E>	An iterator that iterates one element.
Dates	Utilities for java.util.Date
DualCollection<T>	A combination of two collections into a collection.
EmptyCacheMap<K,V>	An empty cache map.
FastReadArray<T>	An array of objects that are fast to read but a bit slower to add and remove.
FastReadCache<K,V>	A CacheMap that the possibility to have cache hit is much more than not.
FilterMap<K,V>	A map that allows the value to be evaluated before returning (so called filtering).
IdentityComparator<T>	The comparator uses == and System.identifyHashCode to compare two objects.
IdentityHashSet<T>	Like java.util.InternalHashMap, it uses == and System.identityHashCode for doing HashSet.
Locales	The locale relevant utilities.
Maps	Utilities for process Map.
Maps.SerializableEntry<K,V>	A serializable implement of Map.Entry
MultiCache<K,V>	A CacheMap that uses multiple instanceof CacheMap to speed up the performance.
NotableLinkedList<E>	Linked list implementation of the List interface that provides the callback methods such as NotableLinkedList.onAdd(E, E), NotableLinkedList.onSet(E, E) and NotableLinkedList.onRemove(E).
Pair<X,Y>	A pair of keys.
TimeZones	Utilities to access time-zone.
Utils	Generic utilities.
WaitLock	A simple lock used to implement load-on-demand mechanism.
