abstract class RFC1522Codec extends Object
Implements methods common to all codecs defined in RFC 1522.
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.
