Overview
Utility Classes
A few packages contain some utility classes which are shared by
several of the main APIs. Many such classes are not needed for
module authors, and serve rather as supports for the implementation
code present in API packages. Usually the classes which do need to
be understood by module authors will be linked to from the
appropriate main API. The packages holding utility classes and some
of the more prominent classes in them are:
org.openide.awt:
HtmlBrowser;
UndoRedo;
and a variety of visual components which may be used in modules to
help emulate the appearance and GUI behavior of the rest of the
IDE, such as
SplittedPanel.
org.openide.util:
SharedClassObject;
Mutex;
Task;
HelpCtx;
Utilities;
NbBundle;
HttpServer;
and a few other classes.
org.openide.util.enum:
convenient higher-order enumeration types, to complement the Java
Collections system.
org.openide.util.io:
a few extensions to the Java I/O system.
org.openide.xml:
general XML parsing, entity registration, and so on.
