All Implemented Interfaces:

ByteToCharTransformer, Transformer

public class Base64

extends AbstractTransformer

implements ByteToCharTransformer

Uses the sun.misc classes to do BASE64 encoding and decoding. The sun.misc classes are not supported by Sun. Perhaps once we have to plug in another class.
