Detailed Description

Helper class for RpmDb::getPackages() to build the list<Package::Ptr> returned.

We have to assert, that there is a unique entry for every string.

In the first step we build the _list list which contains all packages (even those which are contained in multiple versions).

At the end buildIndex() is called to build the _index is created and points to the last installed versions of all packages. Operations changing the rpmdb content (install/remove package) should set _valid to false. The next call to RpmDb::getPackages() will then reread the the rpmdb.

Note that outside RpmDb::getPackages() _list and _index are always in sync. So you may use lookup(PkgName) to retrieve a specific Package::Ptr.
