new class. Will handle all sort of information media (Mime mail messages,
1999-08-24 bertrand <Bertrand.Guiheneuf@aful.org> * camel/camel-medium.c (camel_medium_class_init): new class. Will handle all sort of information media (Mime mail messages, Lotus Notes mail messages, postit notes, faxes, who knows .... :) CamelMimePart will inherit from it. * camel/camel-mime-part.c (_set_disposition): (_set_description): description and disposition parameters are now const. * camel/gmime-content-field.c (gmime_content_field_free): added assertion code. * camel/providers/MH/camel-mh-folder.c (_get_message): uses buffered stream. * camel/camel-stream-buffered-fs.c: new stream to accelerate file ops. Thanks to jwz, I've decided to add a level of abstraction to Camel. In the future, it should be able to handle other mail systems, but also non-mail information vehicles. Enough for today. Roller time! svn path=/trunk/; revision=1140
