Class Base64DecoderStream

java.lang.Object

All Implemented Interfaces:
Closeable
public class Base64DecoderStream
extends 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.
