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.
