NAME

Dpkg::Deps::Multiple - base module to represent multiple dependencies

DESCRIPTION

The Dpkg::Deps::Multiple module provides objects implementing various types of dependencies. It is the base class for Dpkg::Deps::{AND,OR,Union}.

METHODS

$dep = Dpkg::Deps::Multiple->new(%opts);: Creates a new object.
$dep->reset(): Clears any dependency information stored in $dep so that $dep->is_empty() returns true.
$dep->add(@deps): Adds new dependency objects at the end of the list.
$dep->get_deps(): Returns a list of sub-dependencies.
$dep->sort(): Sorts alphabetically the internal list of dependencies.
$dep->arch_is_concerned($arch): Returns true if at least one of the sub-dependencies apply to this architecture.
$dep->reduce_arch($arch): Simplifies the dependencies to contain only information relevant to the given architecture. The non-relevant sub-dependencies are simply removed.
This trims off the architecture restriction list of Dpkg::Deps::Simple objects.
$dep->has_arch_restriction(): Returns the list of package names that have such a restriction.
$dep->profile_is_concerned(): Returns true if at least one of the sub-dependencies apply to this profile.
$dep->reduce_profiles(): Simplifies the dependencies to contain only information relevant to the given profile. The non-relevant sub-dependencies are simply removed.
This trims off the profile restriction list of Dpkg::Deps::Simple objects.
$dep->is_empty(): Returns true if the dependency is empty and doesn't contain any useful information. This is true when a (descendant of) Dpkg::Deps::Multiple contains an empty list of dependencies.
$dep->merge_union($other_dep): This method is not meaningful for this object, and will always croak.
