Ruby的继承机制允许一个类(子类)继承另一个类(父类)的属性和方法。这有助于减少代码重复和提高代码的可维护性。以下是一些使用Ruby继承机制提高代码可读性的方法:
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
总之,使用有意义的类名、模块、super关键字、实例变量和实例方法以及清晰的继承层次结构,可以帮助提高Ruby代码的可读性和可维护性。
