contains information for a single unique package
There can be any number of versions of a given package. Package exists in a singly linked list of package records starting at the hash index of the name in the pkgCache::Header::PkgHashTable
A package can be created for every architecture so package names are not unique, but it is guaranteed that packages with the same name are sequencel ordered in the list. Packages with the same name can be accessed with the Group.
| map_id_t ID |
unique sequel ID
ID is a unique value from 0 to Header->PackageCount assigned by the generator. This allows clients to create an array of size PackageCount and use it to store state information for the package map. For instance the status file emitter uses this to track which packages have been emitted already.
Referenced by pkgDPkgPM::Go().
| map_number_t InstState |
installation state of the package
This should be "ok" but in case the installation failed it will be different.
| map_pointer<Version> VersionList |
Base of a singly linked list of versions.
Each structure represents a unique version of the package. The version structures contain links into PackageFile and the original text file as well as detailed information about the size and dependencies of the specific package. In this way multiple versions of a package can be cleanly handled by the system. Furthermore, this linked list is guaranteed to be sorted from Highest version to lowest version with no duplicate entries.
