You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: cache.rb
    path of file: ./repos/metasploit-framework/lib/msf/core/module_manager
    
    the code of the file until where you have to start completion: # -*- coding: binary -*-
#
# Gems
#
require 'active_support/concern'

# Concerns the module cache maintained by the {Msf::ModuleManager}.
module Msf::ModuleManager::Cache
  extend ActiveSupport::Concern

  MEMORY = :memory
  FILESYSTEM = :filesystem
  # Returns whether the cache is empty
    
  def refresh_cache_from_module_files(module_class_or_instance = nil)
    if module_class_or_instance
      Msf::Modules::Metadata::Cache.instance.refresh_metadata_instance(module_class_or_instance)
    else
      module_sets =
          [
              ['exploit', @framework.exploits],
              ['auxiliary', @framework.auxiliary],
              ['post', @framework.post],
              ['payload', @framework.payloads],
              ['encoder', @framework.encoders],
              ['nop', @framework.nops],
              ['evasion', @framework.evasion]
          ]
      @framework.payloads.recalculate # Ensure all payloads are calculated before refreshing metadata
      Msf::Modules::Metadata::Cache.instance.refresh_metadata(module_sets)
    end
