Job::MakeImageDl::JigdoDownload Class Reference

#include <jigdodownload.hh>

Inheritance diagram for Job::MakeImageDl::JigdoDownload:

Job::SingleUrl Job::DataSource::IO Gunzip::IO

List of all members.


Detailed Description

Private class of MakeImageDl: Object extending a SingleUrl and used to retrieve the data of the .jigdo file.

NB: The underlying Download's io pointer is set up to point to this object. Once this receives the calls, this object passes them on to its own io pointer, which will point to the corresponding front-end object, e.g. a GtkSingleUrl. This sandwiching is in contrast to "normal" single-file downloads, where the Download directly calls the GtkSingleUrl.
