## Detailed Description

Same as APT::PackageContainerInterface, just for Versions

## Member Function Documentation

## ◆ getCandidateVer()

|  | pkgCache::PkgIterator const & | Pkg,
|  | CacheSetHelper & | helper )
| staticprotected

returns the candidate version of the package

Parameters

  Cache | to be used to query for information
  Pkg | we want the candidate version from this package
  helper | used in this container instance

## ◆ getInstalledVer()

pkgCache::VerIterator getInstalledVer | ( | pkgCacheFile & | Cache,
|  | pkgCache::PkgIterator const & | Pkg,
|  | CacheSetHelper & | helper )
| staticprotected

returns the installed version of the package

Parameters

  Cache | to be used to query for information
  Pkg | we want the installed version from this package
