输入第一行代码:import logging;logging.basicConfig(level==logging.INFO) 提示:this inspection detects names that should resolved but don't. Due to dynamic dispatch and duck typing, this is possible in a limited but useful number of cases. Top-level and class-le…
Dynamic dispatch动态调度.动态分发 In computer science, dynamic dispatch is the process of selecting which implementation of a polymorphic operation (method or function) to call at run time. It is commonly employed in, and considered a prime characteristic of…

Normally, in a typed language, the dispatch mechanism will be performed based on the type of the arguments (most commonly based on the type of the receiver of a message). This might be dubbed 'per-type dynamic dispatch'. Languages with weak or no typ…
https://developer.apple.com/swift/blog/?id=39 Increasing Performance by Reducing Dynamic Dispatch Like many other languages, Swift allows a class to override methods and properties declared in its superclasses. This means that the program has to dete…
阅读目录: 一. 为什么是它们三个 二. 能够任意赋值的原因 三. dynamic的用法 四. 使用dynamic的注意事项 一. 为什么是它们三个? 拿这三者比较的原因是它们在使用的时候非常相似.你可以用它们声明的变量赋任何类型的值. 看看下面的示例: var a = 1; object b = 1; dynamic c = 1; 你还可以使用关键字为它们赋上更加复杂的类型 var a = new string[]{"1"}; object b = new string[]{&quo…
These instructions perform dynamic lookup of class and generic methods. The class_method and super_method instructions must reference Swift native methods and always use vtable dispatch. The objc_method and objc_super_method instructions must referen…
情况一:导包import时发生错误,请参考这两位 https://blog.csdn.net/zhangyu4863/article/details/80212068https://www.cnblogs.com/biyuting/p/6262599.html 情况二:调用函数是发生这种错误,那么可能是有多个库函数均含有所调用的函数,IDE不知道用哪个. 点击函数左边小灯泡,前两个选一个,进而选择自己需要使用的包…
转载于:http://weishu.me/2017/11/23/dexposed-on-art/ 两年前阿里开源了 Dexposed 项目,它能够在Dalvik上无侵入地实现运行时方法拦截,正如其介绍「enable 'god' mode for single android application」所言,能在非root情况下掌控自己进程空间内的任意Java方法调用,给我们带来了很大的想象空间.比如能实现运行时AOP,在线热修复,做性能分析工具(拦截线程.IO等资源的创建和销毁)等等.然而,随着A…
