NAME¶

DESCRIPTION¶

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).

($check, $param) = $facts->check_package($package)

$check is one when the package is found. For a real package, $param contains the version. For a virtual package, $param contains an array reference containing the list of packages that provide it (each package is listed as [ $provider, $relation, $version ]).

This function is obsolete and should not be used. Dpkg::Deps::KnownFacts is only meant to be filled with data and then passed to Dpkg::Deps methods where appropriate, but it should not be directly queried.

$facts->evaluate_simple_dep()

This method is private and should not be used except from within Dpkg::Deps.
