Dynamic ref to objects

Former Member — Thu, 24 May 2007 07:11:23 GMT

Hallo Buddies,

I have a scenario where I have to create the object of class dynamically,

The scenario is like this:

User inputs the class name, and I have to create the object of the user input class dynamically.

Here, I know the interface of the user input class, and hence can get the reference to interface which I can point to the object created dynamically from the user input class.

How can I do it? A code snippet will do a lot of help.

Thanks and Regards,

Ankit

Hi Ankit,

Check this sample... and change according to your requirement.

DATA: BEGIN OF obj_sales_order

sales_order_no LIKE <sales_order_no_type>,

<...>,

objref TYPE REF TO <SALES_ORDER_CLASS>

END OF obj_sales_order,

reftab LIKE SORTED TABLES OF obj_sales_order

WITH UNIQUE KEY sales_order_no

<other key attributes>.

Now all you need to do is to do a SELECT...ENDSELECT loop, and:

SELECT ...

obj_sales_order-sales_order_no = <selection result>

obj_sales_order-<other key attr> = <selection result>

READ TABLE reftab INTO obj_sales_order

FROM obj_sales_order.

IF sy-subrc <> 0.

CREATE OBJECT obj_sales_order-objref

EXPORTING ...

EXCEPTIONS ...

IF sy-subrc <> 0.

MESSAGE ...

CONTINUE.

ELSE.

INSERT obj_sales_order INTO TABLE reftab.

ENDIF.

CALL METHOD obj_sales_order-objref-><method>.

ENDSELECT.

Raj

parameter p_cls(30)

data obj type ref to <interface>.

CREATE OBJECT obj TYPE (p_cls).

Reward with points, if useful.
