org.jboss.seam.util.Base64.InputStream
public static class Base64.InputStream
A Base64.InputStream will read data from another
java.io.InputStream, given in the constructor,
and encode/decode to/from Base64 notation on the fly.

public Base64.InputStream(InputStream in)
Base64.InputStream in DECODE mode.
in - the java.io.InputStream from which to read data.
public Base64.InputStream(InputStream in,
int options)
Base64.InputStream in
either ENCODE or DECODE mode.
Valid options:
ENCODE or DECODE: Encode or Decode as data is read.
DONT_BREAK_LINES: don't break lines at 76 characters
(only meaningful when encoding)
Note: Technically, this makes your encoding non-compliant.
Example: new Base64.InputStream( in, Base64.DECODE )
in - the java.io.InputStream from which to read data.options - Specified optionsBase64.ENCODE,
Base64.DECODE,
