interface of message body parts.
Definition bodypart.h:45
virtual MimeTreeParser::ObjectTreeParser * objectTreeParser() const =0
For making it easier to refactor, add objectTreeParser.
virtual MimeTreeParser::NodeHelper * nodeHelper() const =0
Ok, this is ugly, exposing the node helper here, but there is too much useful stuff in there for real...
virtual KMime::Content * content() const =0
Returns the KMime::Content node represented here.
virtual bool decryptMessage() const =0
Return true if an encrypted mail should be decrypted.
