NAME
       Dpkg::Deps::KnownFacts - list of installed real and virtual packages

DESCRIPTION
       This class represents a list of installed packages and a list of virtual packages provided
       (by the set of installed packages).

METHODS
       $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).

       $facts->evaluate_simple_dep()
           This method is private and should not be used except from within Dpkg::Deps.

CHANGES
   Version 2.00 (dpkg 1.20.0)
       Remove method: $facts->check_package().

   Version 1.01 (dpkg 1.16.1)
       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check_package() is obsolete, it should not have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.

   Version 1.00 (dpkg 1.15.6)
       Mark the module as public.

1.21.1                                      2025-09-09              Dpkg::Deps::KnownFacts(3perl)
