Dpkg::Deps::KnownFacts(3perl)

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.
