mod.instance_methods(include_super=true)   → array

Returns an array containing the names of public instance methods in the receiver. For a module, these are the public methods; for a class, they are the instance (not singleton) methods. With no argument, or with an argument that is false, the instance methods in mod are returned, otherwise the methods in mod and mod’s superclasses are returned.

module A
  def method1()  end
end
class B
  def method2()  end
end
class C < B
  def method3()  end
end

A.instance_methods                #=> ["method1"]
B.instance_methods(false)         #=> ["method2"]
C.instance_methods(false)         #=> ["method3"]
C.instance_methods(true).length   #=> 43
