public final class EncodedInputStream
extends java.io.InputStream

Create an encoded stream from a Reader. This is an internal class, used to pass readers of characters as streams of bytes. The characters will be represented according to the specified encoding. It is up to the caller to ensure the specified encoding is available, and in general only encodings available as default from Java 1.3 and up should be used. Currently, the encodings 'UTF8' and 'UTF-16BE' are used. Streams are obtained by calling the static methods of this class, for instance createUTF8Stream.
