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…

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…

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…

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…

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…
