Calling child methods in parent

ruby-talk
1

Hi-
   This may be a pretty easy question but I'm new to ruby

Say I have a class like this

class MyClass

  def myCallingMethod
      myMethodToOverrider("hello")
  end

   def myMethodToOverride(string)

    end
end

and I want to create a chile method like so

class ChildClass < MyClass
    def myMethodToOverride(string)
         puts string
     end
end

Then I create an instance of my child class

child = ChildClass.new()

then I call myCallingMethod

child.myCallingMethod()

is there anyway to have the method in the parent object call the overriden
method in the child?

Thanks in advance.

That's the default behaviour, actually. In C++ terms, all methods are virtual.

Observe:

  class Parent
    def say_what
      virtual_method("Hello World")
    end
    def virtual_method(str)
      "I say: #{str}"
    end
  end

  class Child < Parent
    def virtual_method(str)
      "My parent says: #{str}"
    end
  end

  william = Parent.new
  william.say_what
  # => "I say: Hello World"

  billy = Child.new
  billy.say_what
  # => "My parent says: Hello World"
