如何获取在Ruby的子类中定义的方法的列表？

Question

Let's say I have some ruby code like this:

class ParentClass
   def method1
     # some code
   end
end

class MyAwesomeSubclass < ParentClass
  def method1
    # some code
  end

  def method2
    # more code
  end
end

Is there a way to get a list of method defined on the subclass, so [:method1, :method2] in this example? My first impulse was to say MyAwesomeSubclass.methods - ParentClass.methods , but this would remove :method1 since method1 is defined on the parent class also. I need a list of all methods that are defined by a subclass.

Thanks for your help.

Try MyAwesomeSubclass.instance_methods(false) ? I believe that's what you're looking for...
