在SAP ABAP编程中,面向对象编程(Object-Oriented Programming,简称OOP)是一种强大的编程范式,它允许开发者更好地组织和重用代码。其中,动态分派(Dynamic Dispatch)是OOP的一个关键概念,它涉及到在运行时根据对象的实际类型来调用相应的方法。 1. 动态分派概述 动态分派是一种多态性的实现方式,它允许在运行时根据对象...
The object-orientation modeling of a software system is the most important, most time-consuming, and most difficult requirement for attaining the above goals. Object-oriented design involves more than just object-oriented programming, and provides logical advantages that are independent of the actual i...

This book:- Shows how object-oriented principles apply to ABAP program design- Provides the basics for creating component design diagrams- Teaches how to incorporate design patterns in ABAP programsWhat You'll Learn- Write ABAP code using the object-oriented model as comfortably and easily as ...
Object-oriented programming is based on the encapsulation of data and functions in classes. Instances (objects) are then created from these classes. ABAP supports polymorphism by the use of simple inheritance and interfaces. Classes and interfaces can be created locally in any ABAP program or global...
class1⇒name1 = 'ABAP Object Oriented Programming'. class1⇒data1 = 0. Data: Object1 Type Ref To class1, Object2 Type Ref To class1. Create Object: Object1, Object2. CALL Method: Object1→meth1, Object2→meth1. 复制 上面的代码产生以下输出 - 构造...

Object oriented programming follows bottom-up approach ABAP 运行时环境在分配导入参数 class1_prgm 期间执行隐式转换。此功能有助于通用地实现 start 方法。与对象引用变量相关联的动态类型信息允许 ABAP 运行时环境将方法调用与对象引用变量指向的对象中定义的实现动态绑定。例如,class_type_approach 类中方法 start...
