Class DefaultPageCreator

java.lang.Object

org.htmlunit.DefaultPageCreator

All Implemented Interfaces:

Serializable, PageCreator

public class DefaultPageCreator
extends Object
implements PageCreator, Serializable

The default implementation of PageCreator. Designed to be extended for easier handling of new content types. Just check the content type in createPage() and call super(createPage()) if your custom type isn't found. There are also protected createXXXXPage() methods for creating the Page types which HtmlUnit already knows about for your custom content types.

The following table shows the type of Page created depending on the content type:

Content type	Type of page
text/html text/javascript	HtmlPage
text/xml application/xml text/vnd.wap.wml *+xml	XmlPage, or an XHtmlPage if an XHTML namespace is used
text/*	TextPage
Anything else	UnexpectedPage
