All Implemented Interfaces:

Closeable

public class UUDecoderStream
extends FilterInputStream

An implementation of a FilterOutputStream that decodes the stream data in UU encoding format. This version does the decoding "on the fly" rather than decoding 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.
