ABAP Objects-attribute accessability issue

Former Member — Thu, 28 Jul 2005 10:30:51 GMT

Hi,

Let me introduce the problem.

I have a class c1 which has a public attribute a1.

a1 is of table type which refers to a class c2. c2 has an attribute a2 which is public.

With the object o1 of class c1 I need to access a2.

Please help me solve the problem.

Regards,

Ravi

Ok, let me give the actual classes and attributes.

The class c1 is "cl_merep_syncbo_meta"

a1 is "field_groups"

field_groups is declared as follows(in the public section of c1):

data FIELD_GROUPS type MEREP_TSYNCBO_FIELD_GROUP read-only .

MEREP_TSYNCBO_FIELD_GROUP is a table type which refers to class CL_MEREP_SYNCBO_FIELD_GROUP (class c2 say)

c2 has the attribute NAME.

I have an object of class c1 as "syncboaccessor"

I tried with this:

syncboaccessor->field_groups->name.

The error I get is "field_groups is not a reference variable".

Regards,

Ravi

Hi !

if i well undestood your problem this code should works fine..

data: c1 type ref to zc1,

c2 type ref to zc2.

ZTAB is a table type containing references of classes ZC2

data: tab type ztab,

wa like line of tab.

create object c1.

create object c2.

set values in c2

c2->a2 = 'X'.

append c2 into c1 table

append c2 to c1->a1.

for all entries in c1 table, retrieve the object reference and prints a2

loop at c1->a1 into wa.

write wa->a2.

endloop.

Best regards, Manuel

class a definition.

data : obj2 type ref to b.

methods : write_data.

endclass.

class b definition.

public section.

data : v_num type i.

methods : assign_value.

endclass.

class a implementation.

method write_data.

create object obj2.

call method obj2->assign_value.

write:/1 'Hello Everybody'.

endmethod.

endclass.

class b implementation.

method assign_value.

v_num = 100.

endmethod.

endclass.

data : obj1 type ref to a.

start-of-selection.

create object obj1.

call method obj1->write_data.

write:/1 obj1->obj2->v_num.
