## 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.
