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).
- $facts->evaluate_simple_dep()
- This method is private and should not be used except from within
Dpkg::Deps.
Remove method:
$facts->check_package().
New option:
$facts->add_installed_package() now
accepts 2 supplementary parameters ($arch and
$multiarch).
Deprecated method:
$facts->check_package() is obsolete, it
should not have been part of the public API.
Mark the module as public.
