#input_klass ⇒ Object

重要！在分析前需要确定input_klass input_klass 的类为input模块的类Aio::Module::InputStyle

#invalid?(context) ⇒ Boolean

判断 context 是否有效

Returns:

  • (Boolean)

def invalid?(context)
  return true if context.empty?
  return true if @invalid_input.match(context[1])
  return false
end

#parse_by_compare(compare_klass) ⇒ Object

通过output/compare_xml生成的XML文件解析，直接将结果保存compare_klass 为比较模块其中只比较useful的值，并不会去比较warning warning 有原本device中以及比较中共同得出

#parse_by_module ⇒ Object

通过巡检文件的方式获得关键信息，并按cmd模块逐个解析
