NAME

6       Dpkg::Deps::KnownFacts - list of installed real and virtual packages
7

DESCRIPTION

9       This class represents a list of installed packages and a list of
10       virtual packages provided (by the set of installed packages).
11

METHODS

13       $facts = Dpkg::Deps::KnownFacts->new();
14           Creates a new object.
15
16       $facts->add_installed_package($package, $version, $arch, $multiarch)
17           Records that the given version of the package is installed. If
18           $version/$arch is undefined we know that the package is installed
19           but we don't know which version/architecture it is. $multiarch is
20           the Multi-Arch field of the package. If $multiarch is undef, it
21           will be equivalent to "Multi-Arch: no".
22
23           Note that $multiarch is only used if $arch is provided.
24
25       $facts->add_provided_package($virtual, $relation, $version, $by)
26           Records that the "$by" package provides the $virtual package.
27           $relation and $version correspond to the associated relation given
28           in the Provides field (if present).
29
30       $facts->evaluate_simple_dep()
31           This method is private and should not be used except from within
32           Dpkg::Deps.
