Dpkg::Deps::KnownFacts − list of installed real and virtual packages
This class represents a list of installed packages and a list of virtual packages provided (by the set of installed packages).
$facts = Dpkg::Deps::KnownFacts−>new();
Creates a new object.
$facts−>add_installed_package($package, $version, $arch, $multiarch)
Records that the given version of the package is installed. If $version/$arch is undefined we know that the package is installed but we don’t know which version/architecture it is. $multiarch is the Multi-Arch field of the package. If $multiarch is undef, it will be equivalent to "Multi-Arch: no".
Note that $multiarch is only used if $arch is provided.
$facts−>add_provided_package($virtual, $relation, $version, $by)
Records that the "$by" package provides the $virtual package. $relation and $version correspond to the associated relation given in the Provides field (if present).
This method is private and should not be used except from within Dpkg::Deps.
Remove method: $facts−>check_package().
New option: Dpkg::Deps::KnownFacts−>add_installed_package() now accepts 2 supplementary parameters ($arch and $multiarch).
Deprecated method: Dpkg::Deps::KnownFacts−>check_package() is obsolete, it should not have been part of the public API.
Mark the module as public.
