Detailed Description

template<typename Str, typename Itr>
struct pkgCache< Str, Itr >::Version

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

VerMultiArch

template<typename Str , typename Itr >

enum VerMultiArch

Multi-Arch capabilities of a package version.

Enumerator
No	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

Member Data Documentation

FileList

template<typename Str , typename Itr >

map_pointer<VerFile> 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.

Hash

template<typename Str , typename Itr >

uint32_t Hash

characteristic value representing this version

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

MultiArch

template<typename Str , typename Itr >

map_number_t MultiArch

stores the MultiArch capabilities of this version

Flags used are defined in pkgCache::Version::VerMultiArch

ParentPkg

template<typename Str , typename Itr >

map_pointer<Package> ParentPkg

links to the owning package

This allows reverse dependencies to determine the package

Size

template<typename Str , typename Itr >

map_filesize_t Size

archive size for this version

For Debian this is the size of the .deb file.
