public class HTMLInputStream
extends InputStream

A InputStream on top of a IHTMLReader.

Allows to treat a reader as an InputStream. The reader can be a IHTMLFilter allowing a HTML document to be processed in a streaming manner.

Characters from the reader are converted to bytes either by using the encoding of the reader (e.g. the encoding of the original documnet) or by specifying an encoding explicitly.
