Detailed Description

information for a single version of a package

The version list is always sorted from highest version to lowest version by the generator. Equal version numbers are either merged or handled as separate versions based on the Hash value.

Member Enumeration Documentation

enum pkgCache::Version::VerMultiArch

Multi-Arch capabilities of a package version.

Enumerator
None	is the default and doesn't trigger special behaviour
All	will cause that Ver.Arch() will report "all"
Foreign	can satisfy dependencies in another architecture
Same	can be co-installed with itself from other architectures
Allowed	other packages are allowed to depend on thispkg:any
AllForeign
AllAllowed

Member Data Documentation

map_ptrloc pkgCache::Version::DependsList

base of the dependency list

map_ptrloc pkgCache::Version::DescriptionList

next description in the linked list

map_ptrloc pkgCache::Version::FileList

references all the PackageFile's that this version came from

FileList can be used to determine what distribution(s) the Version applies to. If FileList is 0 then this is a blank version. The structure should also have a 0 in all other fields excluding pkgCache::Version::VerStr and Possibly pkgCache::Version::NextVer.

unsigned short pkgCache::Version::Hash

characteristic value representing this version

No two packages in existence should have the same VerStr and Hash with different contents.

unsigned int pkgCache::Version::ID

unique sequel ID

unsigned long long pkgCache::Version::InstalledSize

uncompressed size for this version

unsigned char pkgCache::Version::MultiArch

stores the MultiArch capabilities of this version
