User-Defined Data Types (Java Enterprise in a Nutshell)David FlanaganJim Farley
在前面曾经介绍过,ABAP共有8种基本数据类型,但是这些数据类型属性太为单一,为了方便开发人员操作和理解,SAP还提供自定义数据类型,让用户能自行定义数据类型的名称及属性,通过关键字TYPES能够实现自定义功能,其语法格式与变量定义类似,通过TYPES声明的参数可以被其它常量、变量引用,不能直接赋值。 FOR EXAMPLE: TYPES name...

User Defined Exit Types About Return Parameters in Java Action Processors Parameters are returned individually as a name value pair using the following API calls: returnCSDLParam returnRollbackParam returnInfoParam returnGlobalParam Parameters can also be returned in a properties list which can...
You can create a custom scalar user-defined function (UDF) using either a SQL SELECT clause or a Python program. The new function is stored in the database and is available for any user with sufficient privileges to run. You run a custom scalar UDF in much the same way as you run exi...
What are user-defined / program-defined types? Back in the introduction to the previous chapter (12.1 -- Introduction to compound data types), we introduced the challenge of wanting to store a fraction, which has a numerator and denominator that are conceptually linked together. In that lesson...
First, APLX looks to see if the symbol refers to a member defined in the class of the object. If not, it looks to see if the member is defined in the parent class (if any), iterating through each of the ancestors in turn.
