Groovy中@Delegate和@Mixin AST转换之间的区别

也许我的问题与OO有关,当应用不同的模式,但是我使用两者,我可以实现相同的行为.

class Person {
    String name = "Clark"
    def walk() { "Walk" }
}

@Mixin(Person)
class Superhero {
    def fly() { "Fly" }
}

def superman = new Superhero()
assert superman.name == "Clark"
assert superman.walk() == "Walk"
assert superman.fly() == "Fly"

class Person {
    String name = "Clark"
    def walk() { "Walk" }
}

class Superhero {
    @Delegate Person person
    def fly() { "Fly" }
}

def superman = new Superhero(person: new Person())
assert superman.name == "Clark"
assert superman.walk() == "Walk"
assert superman.fly() == "Fly"
