Description

Interface Summary

CommandParser.Converter<T>	An interface for an object which converts a String to a value.
Copyable	Objects that implement the Copyable are capable of copying their internal, persistent state to another object that can be cast to the same type.
DynamicPropertySet	This class can be used by objects that need to manage a dynamic set of properties.
Filter<T>	A simple filter interface.
Log.Formatter	An object which formats a value into a StringBuffer.
Maps.BaseEntry<K,V>	The extended Map.Entry interface required by Maps.AbstractHashMap for its entries.
Maps.LinkedEntry<K,V>	The Map.Entry (and Maps.BaseEntry) extended interface required by Maps.AbstractLinkedHashMap for its entries.
Maps.ManagedCacheMapMBean
Maps.TimedEntry<K,V>
PairList<A,B>	PairList extends List interface to support Pair types which are in turn made of two arbitrary types.
ResourcePicker.ResourceBase	A label interface that says to restart the lable tree from here.
ResourcePicker.ResourceFree	A label interface that implies that whilst the panel is named it doesn't have any interesting properties to be set so it can be ignored.

Class Summary

AccessibleUtils	The AccessiblityUtils class provides helper methods for dealing with accessiblity.
ArrayIterator<E>	The ArrayIterator class iterates over an array.
ArrayMap<K,V>	A map stored in arrays, suitable for a small number of entries.
ArrayPairList<A,B>	ArrayPairList is an ArrayList that extends ArrayList and implements the PairList (which extends the List interface) to support Pairs of generic types, say Pair of A,B.
ArraySortedSet<E>	The ArraySortedSet is an array implementation of the SortedSet interface.
BundleLoader	By default the strategy for fetching resource bundles requires a large number of class and resource fetches; the method ResourceBundle.getBundle(String,Locale,ClassLoader) gives precise details.
CamelCaseFilter	Verifies is strings match a CamelCase filter.
ChangeSupport	A support class for classes which allow ChangeListeners.
CharArrayCharSequence	A CharSequence that wraps a char array.
ClassLoaderProxy	ClassLoaderProxy extends ClassLoader and delegates to the ClassLoader returned from the abstract getDelegate() method.
CommandModel	A model of a command line.
CommandParser	A simple command line parser.
CompositeIterator<T>
CopyOnWriteList	Deprecated. Use CopyOnWriteArrayList
DateComparator	Compares dates.
DynamicPropertySetImpl	Implementation of the DynamicPropertySet interface.
EnumerationStack	A usefull class to put together a group of Enumerations into one big one.
EnvironmentVariables	Deprecated. since 11.1.1 - Use System.getenv().
Executors
Filter.Instances
FormatBundle	A formatting resource provider that wraps a java.util.ResourceBundle.
GraphicsUtils	GraphicsUtils defines common user-interface related utility functions.
Holder<T>	A mutable holder class modeled on the JAX-WS 2.0 Holder class that simply provides a common way of providing an in/out parameter without the need to resort to untidy one length array parameters.
ImageIconCache	An application-wide per-URL cache of ImageIcons.
ImmutableList<E>	An immutable list which wraps an array without copying.
IterablesIterator<T>	An iterator over multiple iterables.
JdkIntrospector	Provides basic information about the J2SE installation that it is run in.
JdkSystemProperties	Stores the system properties of the JDK running the main method into a file.
LineIterator	An iterator on the lines of an input stream or reader.
ListUtil
Log	A simple error and trace log.
MacroExpander	Parses and substitites macros with literal values or other macros.
Maps	An aggregation of abstract and concrete implementations of the Maps.AbstractHashMap interface which address various usage scenarios.
Maps.AbstractHashMap<K,V,E extends Maps.BaseEntry<K,V>>	An abstract, but nearly complete, implementation of the Map interface that is functionally equivalent to HashMap but that allows subclasses to do any or all of the following: control the concrete class of Map.Entry instances used so long as they extend Maps.BaseEntry (see Maps.AbstractHashMap.createEntry(int, K, V, E)); override the calculation of hashCode and equals for all keys (see Maps.AbstractHashMap.keyHashCode(java.lang.Object) and Maps.AbstractHashMap.keyEquals(java.lang.Object, java.lang.Object)); override the calculation of hashCode and equals for all values (see Maps.AbstractHashMap.valueHashCode(java.lang.Object) and Maps.AbstractHashMap.valueEquals(java.lang.Object, java.lang.Object)); track when the map is constructed, initialized, and changed (see Maps.AbstractHashMap.mapConstructed(), Maps.AbstractHashMap.mapInitialized(), and Maps.AbstractHashMap.mapChanged()).
Maps.AbstractLinkedHashMap<K,V,E extends Maps.LinkedEntry<K,V>>	An abstract, but nearly complete, implementation of the Map interface that is functionally equivalent to LinkedHashMap but is based on Maps.AbstractHashMap and allows subclasses the same customization options.
Maps.BoundedLruCacheStrategy<K,V>	A bounded size LRU (least recently used) cache strategy.
Maps.CacheMap<K,V>
Maps.CacheStrategy<K,V>	An abstract caching strategy for a cache map.
Maps.EvictedLinkedEntry<K,V>
Maps.ManagedCacheMap<K,V>	A cache map which is an MBean and can be monitored by a JMX client (e.g., JConsole).
Maps.SoftEntry<K,V>	An Maps.BaseEntry implementation which holds its value with a SoftReference.
Maps.SoftHashMap<K,V>	An implementation of Maps.AbstractHashMap, based on Maps.SoftEntry, which holds its values with SoftReferences.
Maps.SoftLinkedEntry<K,V>	An Maps.LinkedEntry implementation which holds its value with a SoftReference.
Maps.SoftLinkedHashMap<K,V>	An implementation of Maps.AbstractLinkedHashMap, based on Maps.SoftLinkedEntry, which holds its values with SoftReferences.
Maps.StrongEntry<K,V>	The default Maps.BaseEntry implementation.
Maps.StrongHashMap<K,V>	The default implementation of Maps.AbstractHashMap, based on Maps.StrongEntry.
Maps.StrongLinkedEntry<K,V>	The default Maps.LinkedEntry implementation.
Maps.StrongLinkedHashMap<K,V>	The default implementation of Maps.AbstractLinkedHashMap, based on Maps.StrongLinkedEntry.

Maps.UnboundedCacheStrategy<K,V>	An unbounded cache strategy.
Maps.WeakEntry<K,V>	An Maps.BaseEntry implementation which holds its value with a WeakReference.
Maps.WeakHashMap<K,V>	An implementation of Maps.AbstractHashMap, based on Maps.WeakEntry, which holds its values with WeakReferences.
Maps.WeakLinkedEntry<K,V>	An Maps.LinkedEntry implementation which holds its value with a WeakReference.
Maps.WeakLinkedHashMap<K,V>	An implementation of Maps.AbstractLinkedHashMap, based on Maps.WeakLinkedEntry, which holds its values with WeakReferences.
ModelUtil	Common utility methods.
MultiMap<K,V>	An object that maps keys to collections of values.
NamedTimer	A subclass of Timer that also allows configuring the name and priority of the underlying timer thread.
NullResourceBundle	A resource bundle which has no elements.
Pair<A,B>	Encapsulates a Pair of objects. Note: The toString() method returns the toString() of the first object.
PlatformUtils	PlatformUtils provides a common location from which a component can identify the current platform, without the need for each component to perform its own test of the os.name or os.version properties.
ResourcePicker	This package does some very cunning things in order to traverse a given object and find all the objects inside it that are of type JComponent.
ResourceUtils	Resource string utilities.
StringUtil	String utilities.
SwingClosure	This class is intended to be used as a named or anonymous closure for code that must be run immediately on the Swing/AWT event thread while the caller blocks.
SwingUtils	Utility methods for Swing and Java.
SynchronizedQueue	An unbounded synchronized queue.
Tuple<T1,T2>	A generic immutable 2-tuple.
TypeMap<K,V>	A map from a type and all its subtypes to a value.
Version	Represents the version number of an extension or component.
