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 automata.

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