public class UUEncoderStream
extends FilterOutputStream

An implementation of a FilterOutputStream that encodes the stream data in UUencoding format. This version does the encoding "on the fly" rather than encoding a single block of data. Since this version is intended for use by the MimeUtilty class, it also handles line breaks in the encoded data.
