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.
ContextGlobalProvider	An interface that can be registered in a lookup by subsystems wish to provide a global context actions should react to.
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.
NbBundle.ClassLoaderFinder	Deprecated. Useless.
NbPreferences.Provider	Implementation of NbPreferences methods.
TaskListener	Listener which can be notifies when a task finishes.

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.
NetworkSettings	Useful static methods for getting Network Proxy required for make network connection for specified resource.
NetworkSettings.ProxyCredentialsProvider	Allows NetBeans Platform users to provide own proxy and network credentials separately.
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>	This class provides storage functionality with Weak-referenced entries and new method putIfAbsent.

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

Annotation Types Summary

NbBundle.Messages	Creates a helper class with static definitions of bundle keys.
URLStreamHandlerRegistration	Replacement for URLStreamHandlerFactory within the NetBeans platform.
