All Implemented Interfaces:

Serializable, AbstractDocument.AttributeContext

public class GrammarContext
extends StyleContext

A collection of styles used to render xquery script. This class also acts as a factory for the views used to represent the grammarized 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 grammarized document views.
