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: params_wrapper.rb
    path of file: ./repos/hyperstack/ruby/hyper-operation/lib/hyper-operation/railway
    
    the code of the file until where you have to start completion: module Hyperstack
  class Operation
    class ParamsWrapper

      def initialize(inputs)
        @inputs = inputs
      end

      def lock
        @locked = true
        self
      end

      def to_h
        inputs = @inputs
        if @locked
          inputs = inputs.dup
          self.class.inbound_param
    
        def translate_args(*args, &block)
          name, opts = get_name_and_opts(*args)
          if opts.key?(:type)
            type_method = opts.delete(:type)
            if type_method.is_a?(Array)
              opts[:class] = type_method.first if type_method.count > 0
              type_method = Array
            elsif type_method.is_a?(Hash) || type_method == Hash
              type_method = Hash
              block ||= proc { duck :* }
            end
