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: conditional_config.rb
    path of file: ./repos/nii/nii-core/lib/nii
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
    
    def reverse_merge(other)
      other = other.to_nii_config if other.respond_to? :nii_config
      return other.merge(self)    if other.is_a? ConditionalConfig
      merged = ConditionalConfig.new(condition, other.merge(@options), *self.children.map { |c| c.reverse_merge(other) })
      merged = ConditionalConfig.new(nil, other, merged) if condition
      merged
    end
