ABAP-OO: Create any number of instances

[Former Member]

Hello,

please, look at this simple scenario:

DATA:
  my_class type ref to zcl_xyz.
  create object my_class.

In that case I have just created one instance. Now I need a mechanism to create and identify any number of instance of the type zcl_xyz. <b>That means, I dont know exactly, if I need 5 or 200 instances.</b> Any feasible idea, how to handle that?

Thanks and regards.

You can have an internal table which will store the reference to this object.

eg:

data:

my_class type table of ref to zcl_xyz.

do N times.

create object my_class_tmp.

append my_class_temp to my_class.

enddo.

Hi,

Why don't you use internal table to store the instances of the class.

types: my_class type ref to zcl_xyz,

my_table type standard table of my_class.

Hi,

Declare one static attribute in the class.

Here is the sample code to trap the number of instance created for an object type.

CLASS C1 DEFINITION.

PUBLIC SECTION.

CLASS-DATA CREATE_COUNT TYPE I.

METHODS CONSTRUCTOR.

ENDCLASS.

DATA: O1 TYPE REF TO C1,

O2 LIKE O1,

O3 LIKE O1.

CREATE OBJECT: O1,

O2,

O3.

WRITE: 'Number of created objects:', C1=>CREATE_COUNT.

CLASS C1 IMPLEMENTATION.

METHOD CONSTRUCTOR.

CREATE_COUNT = CREATE_COUNT + 1.

ENDMETHOD.

ENDCLASS.

Hope this hint helps you.
