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

list of OR dependencies

## NAME

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

## 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

- $string = $dep-\>output(\[$fh\])

  The **output()** method uses " \| " to join the list of sub-dependencies.

- $tribool = $dep-\>implies($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.

- $tribool = $dep-\>get\_evaluation($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.
