Class ContentModel

java.lang.Object
javax.swing.text.html.parser.ContentModel
All Implemented Interfaces:
Serializable

public final class ContentModel
extends Object
implements Serializable
A representation of a content model. A content model is basically a restricted BNF expression. It is restricted in the sense that it must be deterministic. This means that you don't have to represent it as a finite state automaton.

See Annex H on page 556 of the SGML handbook for more information.
