Dpkg::Deps::Multiple

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.
