/* The MimeUntypedText class is used for untyped message contents, that is,
|
||
|
|
it is the class used for the body of a message/rfc822 object which had
|
||
|
|
*no* Content-Type header, as opposed to an unrecognized content-type.
|
||
|
|
Such a message, technically, does not contain MIME data (it follows only
|
||
|
|
RFC 822, not RFC 1521.)
|
||
|
|
|
||
|
|
This is a container class, and the reason for that is that it loosely
|
||
|
|
parses the body of the message looking for ``sub-parts'' and then
|
||
|
|
creates appropriate containers for them.
|
||
|
|
|
||
|
|
More specifically, it looks for uuencoded data. It may do more than that
|
||
|
|
some day.
|
||
|
|
|
||
|
|
Basically, the algorithm followed is:
|
||
|
|
|
||
|
|
if line is "begin 644 foo.gif"
|
||
|
|
if there is an open sub-part, close it
|
||
|
|
add a sub-part with type: image/gif; encoding: x-uue
|
||
|
|
hand this line to it
|
||
|
|
and hand subsequent lines to that subpart
|
||
|
|
else if there is an open uuencoded sub-part, and line is "end"
|
||
|
|
hand this line to it
|
||
|
|
close off the uuencoded sub-part
|
||
|
|
else if there is an open sub-part
|
||
|
|
hand this line to it
|
||
|
|
else
|
||
|
|
open a text/plain subpart
|
||
|
|
hand this line to it
|
||
|
|
|
||
|
|
Adding other types than uuencode to this (for example, PGP) would be
|
||
|
|
pretty straightforward.
