public class JavaContext

extends javax.swing.text.StyleContext

implements javax.swing.text.ViewFactory

A collection of styles used to render java text. This class also acts as a factory for the views used to represent the java documents. Since the rendering styles are based upon view preferences, the views need a way to gain access to the style settings which is facilitated by implementing the factory in the style storage. Both functionalities can be widely shared across java document views.
