📛 NAME

Dpkg::Deps::OR - list of OR dependencies

🚀 Quick Reference

Use Case	Command	Description
Create an OR dependency object	my $dep = Dpkg::Deps::OR->new();	Instantiate a new OR dependency list
Output dependency string	$dep->output([$fh])	Print the dependency using " | " joiner
Check implication	$dep->implies($other_dep)	Returns 1, 0, or undef for implication
Evaluate dependency	$dep->get_evaluation($facts)	Evaluate with installed packages and virtuals
Simplify dependency	$dep->simplify_deps($facts, @assumed_deps)	Reduce dependency given known facts

📝 DESCRIPTION

This class represents a list of dependencies of which only one must be met for the dependency to be true. It inherits from Dpkg::Deps::Multiple.

⚙️ METHODS

• $dep->output([$fh]) — The output method uses " | " to join the list of sub-dependencies.
• $dep->implies($other_dep) — Returns 1 when $dep implies $other_dep. Returns 0 when $dep implies NOT($other_dep). Returns undef when there's no implication. $dep and $other_dep do not need to be of the same type.
• $dep->get_evaluation($facts) — Evaluates the dependency given a list of installed packages and a list of virtual packages provided. These lists are part of the Dpkg::Deps::KnownFacts object given as parameters. Returns 1 when it's true, 0 when it's false, undef when some information is lacking to conclude.
• $dep->simplify_deps($facts, @assumed_deps) — Simplifies the dependency as much as possible given the list of facts (see object Dpkg::Deps::KnownFacts) and a list of other dependencies that are known to be true.
