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: fake_function.rb
    path of file: ./repos/metasploit-framework/lib/metasploit/framework/obfuscation/crandomizer/code_factory
    
    the code of the file until where you have to start completion: require 'metasploit/framework/obfuscation/crandomizer/utility'

module Metasploit
  module Framework
    module Obfuscation
      module CRandomizer
        module CodeFactory

          class FakeFunction
            attr_reader :attribute
            attr_reader :return_type
            attr_reader :args
            attr_reader :function_name

            def initialize(func_na
    
            def generate_body
              case return_type
              when 'int'
                rand_return_val = Metasploit::Framework::Obfuscation::CRandomizer::Utility.rand_int
                return_statement = %Q|return #{rand_return_val};|
              when 'char*'
                rand_return_str = Metasploit::Framework::Obfuscation::CRandomizer::Utility.rand_string
                return_statement = %Q|return "#{rand_return_str}";|
              else
                return_statement = ''
              end
