You can use functions and embedding for code reuse and interfaces for polymorphism. In your example you've implemented Speak() method for each type and defined a Speaker interface but then in Output() you don't call Speak(). If you have fields you want available through the Speaker interface then you need to define getter methods for those fields and add them to the interface. You could also add a Speak() method to the Animal type which would then be available on any type that embeds an Animal and would have direct access to any fields on Animal. You could define a Speak() function that all the Speak() methods call for some common functionality. How you structure it depends on what real world problem you're trying to solve. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
