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: signature.rb
    path of file: ./repos/vets-api/modules/claims_api/lib/claims_api/v1/poa_pdf_constructor
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module ClaimsApi
  module V1
    module PoaPdfConstructor
      class Signature
        attr_r
    
        def path
          return @path if @path.present?

          @path = "#{::Common::FileHelpers.random_file_path}.png"
          File.binwrite(@path, Base64.decode64(@data))

          @path
        end
