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.
