Ruby的繼承機制允許一個類(子類)繼承另一個類(父類)的屬性和方法。這有助于減少代碼重復和提高代碼的可維護性。以下是一些使用Ruby繼承機制提高代碼可讀性的方法:
class Animal
# ...
end
class Dog < Animal
# ...
end
class Cat < Animal
# ...
end
module Swimmable
def swim
# ...
end
end
class Dog < Animal
include Swimmable
# ...
end
class Cat < Animal
# ...
end
class Dog < Animal
def speak
super.upcase
end
end
class Dog < Animal
def initialize(*args)
super(*args)
@breed = "Golden Retriever"
end
def breed
@breed
end
end
class Animal
# ...
end
class Mammal < Animal
# ...
end
class Dog < Mammal
# ...
end
class Cat < Mammal
# ...
end
總之,使用有意義的類名、模塊、super關鍵字、實例變量和實例方法以及清晰的繼承層次結構,可以幫助提高Ruby代碼的可讀性和可維護性。
