# Dpkg::Deps::Multiple(3perl)

base module to represent multiple dependencies

## 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(@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\_list = $dep-\>**get\_deps()**

  Returns a list of sub-dependencies.

- $dep-\>**sort()**

  Sorts alphabetically the internal list of dependencies.

- $bool = $dep-\>arch\_is\_concerned($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 removed.

  This trims off the architecture restriction list of Dpkg::Deps::Simple objects.

- @pkgname\_list = $dep-\>**has\_arch\_restriction()**

  Returns the list of package names that have such a restriction.

- $bool = $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 removed.

  This trims off the profile restriction list of Dpkg::Deps::Simple objects.

- $bool = $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.

- $bool = $dep-\>merge\_union($other\_dep)

  This method is not meaningful for this object, and will always croak.
