Hi all,
please cut me some slack, if this is really basic and I'm missing out on something.
I have a requirement to generate a security code (actually a voucher ID like on a gift card).
For gift card type A the ID should look like this: XXXX-XXXX-XXXX-XXXX-XXXX
For gift card type B the ID should look like this: XXXXX-XXXXX-XXXXX-XXXXX
Now I want to tackle this with ABAP OO. I was thinking of an (abstract?) super class "ZCL_SEC_CODE" with two subclasses "ZCL_SEC_CODE_A" and "ZCL_SEC_CODE_B". There should be a method "get_voucher_id" which should return Voucher Type A when called from "ZCL_SEC_CODE_A" and Voucher Type B when called from "ZCL_SEC_CODE_B".
I know (not saying to be an expert) about facade, factory and the like, but am still having problems with this:
ABAP OO doesn't allow me to create the methods with a different signature for "ZCL_SEC_CODE_A" and "ZCL_SEC_CODE_B". But I actually want (from a client perspective) the methods to be returning say a Char24 for Type A and a Char23 for Type B. Of course I could just use a Char24 for both and write the shorter Type B into that, but that's not my point.
Thanks and cheers
Jens
