Interface Summary
AsyncGUIJob Service provider interface (SPI) for executing of time consuming task which results are visible in UI.
Cancellable Service provider interface (SPI) for adding cancel support to various jobs.
ContextAwareAction Interface to be implemented by an action whose behavior is dependent on some context.

Enumerations.Processor<T,R> Processor interface that can filter out objects from the enumeration, change them or add aditional objects to the end of the current enumeration.
HelpCtx.Provider An object implementing this interface is willing to answer the HelpCtx.findHelp() query itself.
Mutex.Action<T> Action to be executed in a mutex without throwing any checked exceptions.
Mutex.ExceptionAction<T> Action to be executed in a mutex, possibly throwing checked exceptions.

Class Summary
ChangeSupport A simple equivalent of PropertyChangeSupport for ChangeListeners.
CharSequences Useful static methods to provide and work with memory efficient CharSequence implementations for ASCII strings.
EditableProperties Similar to Properties but designed to retain additional information needed for safe hand-editing.
Enumerations Factory methods for various types of Enumeration.
Exceptions Useful utility and methods to work with exceptions as described in detail in the NetBeans logging guide.
HelpCtx Provides help for any window or other feature in the system.
ImageUtilities Useful static methods for manipulation with images/icons, results are cached.
MapFormat A text format similar to MessageFormat but using string rather than numeric keys.
Mutex Read-many/write-one lock.
Mutex.Privileged Provides access to Mutex's internal methods.
NbBundle Convenience class permitting easy loading of localized resources of various sorts.
NbCollections Utilities for working with generics.
NbPreferences Provides an implementation of the Preferences API which may be backed by a NetBeans-specific implementation.
Parameters Utilities for checking the values of method parameters.
Queue<T> Deprecated. Use BlockingQueue instead.
RequestProcessor Request processor is Executor (since version 7.16) capable to perform asynchronous requests in a dedicated thread pool.
SharedClassObject Shared object that allows different instances of the same class to share common data.
Task A task that may be executed in a separate thread and permits examination of its status.
Union2<First,Second> A union type which can contain one of two kinds of objects.
Utilities Otherwise uncategorized useful static methods.
WeakListeners A generic weak listener factory.
WeakSet<E> Set which holds its members by using of WeakReferences.
 

Exception Summary
MutexException Encapsulates other exceptions thrown from a mutex method.
NotImplementedException Should be thrown when a feature is not implemented.
TopologicalSortException Exception that signals that a topological sort failed due to unsortable nature of the graph and that provides support for reporting and recovering from that state.
UserCancelException Exception that is thrown when user cancels interaction so the requested result cannot be produced.
UserQuestionException Exception that is thrown when the process is about to perform some action that requires user confirmation.
Utilities.UnorderableException Deprecated. Used only by the deprecated partialSort
