How to use class object from one method to another in class

[former_member383962]

Hello Experts,

I created a class with two methods using SE24.

Methods:

1. Get Data

2. Process Data

In a Get Data method i wrote a below code:

* References declarations
  DATA:
        lref_excel                                     TYPE REF TO zkab_cl_fdt_xl_spreadsheet,
        lref_excel_core                             TYPE REF TO cx_fdt_excel_core.

  DATA: lv_msg type string.

*  * * Internal tables declaration
  DATA:
        lt_worksheet                             TYPE STANDARD TABLE OF STRING,
        lw_worksheets like line of lt_worksheet.

  DATA: wa_worksheet type zkab_st_worksheet.

    TRY.

*     Create object of class to read .xlsx file contents

      CREATE OBJECT lref_excel
        EXPORTING
           document_name = file_name
           xdocument     = file_content.

    CATCH cx_fdt_excel_core INTO lref_excel_core.
      CLEAR lv_msg.

*     Call method to get error message text

      CALL METHOD lref_excel_core->if_message~get_text
        RECEIVING
          RESULT = lv_msg.
*<< Display error message returned in lv_msg >>
      RETURN.
  ENDTRY.

* Call method to get list of worksheets in the .xlsx file

  lref_excel->if_fdt_doc_spreadsheet~get_worksheet_names(
      IMPORTING
        worksheet_names = lt_worksheet ).

from the above code, i created a object called "lref_excel".

Now, i want to use the same object in a "Process data" method. is it possible....??

Because, in a "Process data" method also use the same logic what i wrote in a first method with some extended logics to processing the data.

Any suggestions please...

Thanks in advance...

I guess you could create mref_excel as an attribute of your class instead of the local variable lref_excel (if the get_data & process_data are instance methods). If not, you have the option of using respectively an exporting- and an importing parameter.

I believe, Creating a global attribute in class is a better solution then using ref in export import parameters. Preferably create a Private attribute in class is more meaningful in his case.

[Patrick_vN]

Even if the get_data- & process_data-methods are static methods?

s1252 why do you think so?
I'd prefer to pass the objet, maybe as return parameter.

Hello s1252

Thanks for your response...

I can create lref as an attribute.. but how to pass that exporting parameters to that attribute..

i can't get it...

can you provide some sample codes...

thanks in advance...

If those are static methods , then we better go for import export parameters as Patrick Van Nierop suggested and add them in method signature exporting/returning parameters .

Hi Kabilarasan,

If your methods are static, then you can directly call that method by class name.

Click on pattern, and

1. select ABAP object pattern - press OK
2. give class name and method name - press OK
