java.io.InputStream

java.io.FilterInputStream

org.apache.geronimo.mail.util.Base64DecoderStream

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class Base64DecoderStream
extends java.io.FilterInputStream

An implementation of a FilterInputStream that decodes the stream data in BASE64 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.
