SAP ABAP CLASS OO

OOAThe first step of Object-oriented software development is Object-Oriented Analysis (OOA) In the system analysis stage of software engineering, system analysts must integrate with users to make precise Accurate analysis and clear description summarize

实际上就是定义一个本地类.SyntaxCLASS class DEFINITION DEFERRED [PUBLIC].EffectThis variant of the statement CLASS is used to make the class class known, regardless of the location of the actual definition of the class in the program. It does not introduce a declar

以下是如何创建一个本地类。REPORT zrep_class_local_01.* 定义一个本地类CLASS zlcl_class_local DEFINITION. PUBLIC SECTION. DATA: mv_value TYPE string. " 实例属性 CLASS-DATA: gv_cl_value TYPE string. " 静态属性 METHODS: set_value IMPORTING iv_value TYPE stri

The class is the smallest encapsulation unit in ABAP Objects. A method can therefore use all components of all instances of the same class apart from the components of its own instance. An exception to this rule are subclasses that cannot access the privat

面向对象编程（object oriented programming, oop,面向对象程序设计）：是一种计算机编程框架。基本概念1.对象,是一个现实实体的抽象（数据和程序）（属性和方法）.2.类 ，用来描述具有相同的属性和方法的对象的集合；使用了对象以后，ALV是通过ALV的一个实例（INSTANCE）来显示的。实现步骤1.创建屏幕2.屏幕绘制容器（Customer control）3.定义变量4.创建ALV对象creat object: wcl_containerexporting

背景，在alv展示中，以前用的是REUSE_ALV_GRID_DISPLAY这个函数，现在用cl_salv_table更好。最大的优势就是不需要字段累。REUSE_ALV_GRID_DISPLAY的用法 CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY' EXPORTING "显示界面可编辑字段上修改了数据，回车后就会立即将内表的数据也修改 i_grid_settings = i_grid_settin
