public final class B64Code
extends java.lang.Object
Does not insert or interpret whitespace as described in RFC 1521. If you require this you must pre/post process your data.
Note that in a web context the usual case is to not want linebreaks or other white space in the encoded output.

WriteSession session,
java.io.OutputStream out,
LinkedBuffer lb)
Encodes the byte array into the
LinkedBuffer and flushes
to the OutputStream when buffer is full. |

public static byte[] decode(byte[] input,
int inOffset,
int inLen)
Does not attempt to cope with extra whitespace as described in RFC 1521.
Avoids creating extra copies of the input/output.
Note this code has been flattened for performance.
