All Implemented Interfaces:

ICodec<String>, IDecoder<String,String>, IEncoder<String,String>

public class RFC1522BCodec
extends AbstractRFC1522Codec

Identical to the Base64 encoding defined by RFC 1521 and allows a character set to be specified.

RFC 1522 describes techniques to allow the encoding of non-ASCII text in various portions of a RFC 822 [2] message header, in a manner which is unlikely to confuse existing message handling software.

This class is immutable and thread-safe.
