[reSIProcate] How to get BodyData from SipFrag type content?

["Wenwei Xu" <wxu@xxxxxxxxxxxxx>]

Hi, reSIP developers! I need your help. I have a NOTIFY message of type
SipFrag, which contain some body data. Can someone tell me how to get the
body data out of the message? In the downloaded stack, the getBodyData()
function seems not to be implemented(as seen below). How to implement this
function? Can someone give me some idea?

Thanks very much!!!

Contents::getBodyData() const 
{
   ErrLog( << "Need to implement getBodyData function for " << getType() );
   assert(0);
   return Data::Empty;
}
