## Class Base64DecoderStream

- java.lang.Object

- All Implemented Interfaces:
    Closeable, AutoCloseable

      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.
