# File 'lib/rubocop/lockfile.rb', line 29



def dependencies
  return [] unless parser

  parser.dependencies.values
end


  








  

    #gem_versions(include_transitive_dependencies: true)  
  



  

    


Returns the locked versions of gems from this lockfile.



  





  
Parameters:


    
  
  • 
    include_transitive_dependencies:
    (Boolean)
    (defaults to: true)
—

end


  








  

    #includes_gem?(name)  ⇒ Boolean 
  



  

    


Whether this lockfile includes the named gem, directly or indirectly.
