"You cannot use current statement between CLASS DEFINITION ...and ENDCLASS" 错误

Question

我收到错误提示，您不能在 CLASS DEFINITION .... AND ENDCLASS 之间使用当前语句。以下是 ABAP class.

的示例示例

CLASS c1 DEFINITION. 
  PUBLIC SECTION.     
  STATICS static TYPE i VALUE 10. 
  METHODS add_one.

ENDCLASS. 

CLASS c1 IMPLEMENTATION. 

  METHOD add_one.
      static = static + 1. 
  ENDMETHOD.  

ENDCLASS.

问候，

Answer 1

只允许 DATA 和 CLASS-DATA 在 classes 和接口中声明属性。

在class中，STATICS只允许出现在静态方法的实现部分（用CLASS-METHODS声明）。

Answer 2

STATICS 应在内部过程中声明，并且只能在本地访问。

如果您希望能够在方法之外访问值，您应该将变量声明为普通 class/static 属性：

CLASS c1 DEFINITION. 
  PUBLIC SECTION.     
  CLASS-DATA static TYPE i VALUE 10. 
  METHODS add_one.
ENDCLASS. 

CLASS c1 IMPLEMENTATION. 
  METHOD add_one.
      static = static + 1. 
  ENDMETHOD.  
ENDCLASS.
