Acquire Item - Item to acquire
When an item is instantiated it will add it self to the local list in
- the Owner Acquire class. Derived classes will then call QueueURI to
- register all the URI's they wish to fetch at the initial moment.
-
+ the Owner Acquire class. Derived classes will then call QueueURI to
+ register all the URI's they wish to fetch at the initial moment.
+
Three item classes are provided to provide functionality for
downloading of Index, Translation and Packages files.
-
+
A Archive class is provided for downloading .deb files. It does Hash
checking and source location as well as a retry algorithm.
