## javax.swing.text.html.parser
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.

Field Summary
`Object` | `content` The content.
`ContentModel` | `next` The next content model (in a ',', '|' or '&' expression).
`int` | `type` Type.

Constructor Summary
`ContentModel()`
`ContentModel(Element content)` Create a content model for an element.
`ContentModel(int type, ContentModel content)` Create a content model of a particular type.
`ContentModel(int type, Object content, ContentModel next)` Create a content model of a particular type.

Method Summary
`boolean` | `empty()` Return true if the content model could match an empty input stream.
`Element` | `first()` Return the element that must be next.
`boolean` | `first(Object token)` Return true if the token could potentially be the first token in the input stream.
`void` | `getElements(Vector elemVec)` Update elemVec with the list of elements that are part of the this contentModel.
`String` | `toString()` Convert to a string.
