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

list of unrelated dependencies

## NAME

Dpkg::Deps::Union - list of unrelated dependencies

## DESCRIPTION

This class represents a list of relationships. It inherits from Dpkg::Deps::Multiple.

## METHODS

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

  The **output()** method uses ", " to join the list of relationships.

- $dep-\>implies($other\_dep)

  - $dep-\>get\_evaluation($other\_dep)

  These methods are not meaningful for this object and always return undef.

- $dep-\>simplify\_deps($facts)

  The simplification is done to generate an union of all the relationships. It uses `$simple_dep`-\>merge\_union($other\_dep) to get its job done.
