如果用户输入小轿车,就执行小轿车的驾驶方法, 涉及到用户,这些都只能在运行时才能干。运行时的,就是动态的,所以这也是动态方法调度(dynamic method dispatch), 既然是父类指针指向子类,这也是向上转型Upcasting(为什么是向上?看我本章的第一张图:父类 fuLei=(父类)new 子类(); ,,,感觉到一种向上转型的意味吗?

对于single dispatch语言来说,在调用方法时,参数会被特殊处理用于去选择方法实现,在很多语言中,这种特殊参数是在语法上就进行指明的.例如,很多语言会把特殊参数放在调用语言之前special.method(other, arguments, here)但是在multiple dispatch中,选择方法时,也会对参数的个数和类型进行匹配.没有特殊参数去持有方法调用....

前面提过,基于栈式架构的虚拟机所使用的零地址指令更加紧凑,但完成一项操作的时候必然需要使用更多的入栈和出栈指令,这同时也就意味着将需要更多的指令分派(instruction dispatch)次数和内存读/写次数。 由于操作数是存储在内存中的,因此频繁地执行内存读/写操作必然会影响执行速度。为了解决这个问题,HotSpot JVM的设计...

The decision of which version of a method to call may be based either on a single object, or on a combination of objects. The former is called single dispatch and is directly supported by common object-oriented languages such as C++, Java, Smalltalk, Objective-C, Swift, JavaScript, and Py...
动态分派(Dynamic Dispatch)发生在运行时期,动态分派动态地置换掉某个方法。 静态分派 Java通过方法重载支持静态分派。 www.cnblogs.com|基于69个网页 2. 动态调度 上述的情况称之为多态性(polymorphism)或动态调度(dynamic dispatch)。动态调度就是说在程序执行时决定要真正调用的子程 … ...
