ABAP global class method data access in local class

former_member761924 — Wed, 15 Sep 2021 13:17:32 GMT

I'm calling an instance public method of a global class from my local class, an internal table is processed and populated inside this method. How can I access this internal table data from my local class?

Ex - data(lo_object) = NEW zcl_xxxx( ).

lo_object->parse_xml( ).

In this Parse_xml method an internal table gt_header is populated, I want to access this table data in my local class.

Note - this method has no returning parameters.

I'm new to ABAP please excuse me if the question is too basic or insensible.

There is no difference in accessing a global class from a local class or from elsewhere.

Normally, you use local classes as helper classes in global classes and not vice versa.

If you are new to ABAP Objects, you should get used to it by doing simple exercises, you can find in the Web.

In the ABAP documentation, you find the following introduction:

Maybe with this kind of code if the attribute GT_HEADER is public:

DATA(local_copy_of_headers) = lo_object->gt_header.

Or if the attribute is private, maybe there is a public method to return it.

If the attribute is protected, maybe you can create a subclass (INHERITING FROM the global class) which will be able to access the protected attribute, and you can create a public method there to return the attribute.
