使用super 关键字访问父类的非私有属性或调用父类的非私有方法,具体格式如下: super.属性 super.方法(参数 1,参数 2,..) 使用super关键字调用父类中指定的构造方法,具体格式如下: super (参数 1,参数 2,..) 通过super调用父类构造方法的代码必须位于子类构造方法的第一行且只能出现一次。This和super不能同时...

When it encounters a method invocation, the compiler might generate a call to any of several functions to perform the actual message dispatch, depending on the receiver, the return value, and the arguments. You can use these functions to dynamically invoke methods from your own plain C code, ...

类的方法列表的查询通过getMethodNoSuper_nolock->search_method_list方法处理,具体的逻辑不展开了,只需知道若方法列表是排过序的会使用二分搜索去查;否则就是一个简单的遍历查询。所以在没有方法缓存的情况下方法的查询效率是很低的,时间复杂度要么是 O(logn) 要么是 O(n)。
