## 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

## VerMultiArch

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

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

uint32_t Hash

characteristic value representing this version

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

## MultiArch

map_number_t MultiArch

stores the MultiArch capabilities of this version

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

## ParentPkg

map_pointer<Package> ParentPkg

links to the owning package

This allows reverse dependencies to determine the package

## Size

map_filesize_t Size

archive size for this version

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

The documentation for this struct was generated from the following file:
