org.apache.geronimo.mail.util.UUEncoderStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

public class UUEncoderStream
extends java.io.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.
