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

Version1.02(dpkg1.17.10) New methods: Add $dep->profile_is_concerned() and $dep->reduce_profiles(). Version1.01(dpkg1.16.1) New method: Add $dep->reset(). Version1.00(dpkg1.15.6) Mark the module as public. 1.22.21 2025-07-14 Dpkg::Deps::Multiple(3perl)

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

$dep = Dpkg::Deps::Multiple->new(@deps); Creates a new object, with the list of dependencies in @deps. $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.
