Class 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.
