Accessing Objects from a Class

Former Member — Tue, 28 Aug 2007 21:12:54 GMT

Hello,

I have a process that calls a method from a class, at runtime, the object creates a reference and in the reference I need to access an object, basically this is what I have at run time:

Object: WA_OBJECT

Reference:

If I double click on my object I get the following sub objects:

CL_PT_REQ_HEADER

IF_PT_REQ_HEADER~CURRENT_VERSION

IF_PT_REQ_HEADER~MAX_VERSION_NO

IF_PT_REQ_HEADER~MY_REQUEST

ITEM_TAB

if I double click on any of those items, it is fine in debugging, I can see the values, but in my program, I need to access the ITEM_TAB internal table, now I cannot use WA_OBJECT-ITEM_TAB. If I double click on the ITEM_TAB, now the main object becomes -ITEM_TAB[1], so cannot reference to that object in my program, so the question is how do I access the table?

Thanks for any answers.

Hello Enrique

ITEM_TAB is a <i>public </i>instance attribute of class CL_PT_REQ_HEADER. Thus, you can directly access them using

DATA:
  ls_item    TYPE PTREQ_ITEMS_STRUC,
  lo_item    TYPE IF_PT_REQ_ITEM.

  LOOP AT wa_object->item_tab INTO ls_item.
    lo_item = ls_item-item.
  ENDLOOP.

Regards

Uwe

Uwe,

thanks for your prompt answer. Now that you mention it, I forgot to specify the fact that only the first Items are public, but the table is protected and I cannot do a simple loop at it the way you mentioned. That is the first thing I tried but wa_object->item_tab is not recognized when I ckeck syntax. I should have also mentioned that WA_OBJECT gets referenced ar runtime.

Hopefully there is a method of WA_OBJECT which can give you the information you need.

Trying to directly read the contents of a private table is defeating the whole philosophy of object oriented programming.

Hello

I would like to add that you are dealing with a <b>persistence class</b>. Perhaps the following thread may be of use since persistence classes require a specific logic.
