Class HtmlInputStreamReader

java.lang.Object
  java.io.Reader
      nu.validator.htmlparser.io.HtmlInputStreamReader

All Implemented Interfaces:

Closeable, Readable, ByteReadable, Locator

public final class HtmlInputStreamReader
extends Reader
implements ByteReadable, Locator

Be very careful with this class. It is not a general-purpose subclass of of Reader. Instead, it is the minimal implementation that does what Tokenizer needs while being an instance of Reader. The only reason why this is a public class is that it needs to be visible to test code in another package.
