All Implemented Interfaces:

Document, SafelyCloseable, Closeable

Enclosing class:

HtmlDocumentFactory

protected class HtmlDocumentFactory.HtmlDocument
extends AbstractDocument

An HTML document. If a TITLE element is available, it will be used for title() instead of the default value.

We delay the actual parsing until it is actually necessary, so operations like getting the document URI will not require parsing.
