Dpkg::Deps::Multiple − base module to represent multiple dependencies
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(%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.
New methods: Add $dep−>profile_is_concerned() and $dep−>reduce_profiles().
New method: Add $dep−>reset().
Mark the module as public.
