QApt::Backend Class Reference

#include <backend.h>

List of all members.

Detailed Description

The main entry point for performing operations with the dpkg database.

Backend encapsulates all the needed logic to perform most apt operations. It implements the initializing of the database and all requests to/for the database. Please note that you _MUST_ call init() before doing any further operations to the backend, or else risk encountering undefined behavior.
