Object table confusion

[Former Member]

Hi All,

I want to store a number of ZCL_BDC_FIELD objects into an internal table.

What is the easiest eay to do this? Here's my attempt...

Types: begin of ty_field_itab,

fld type ref to ZCL_BDC_FIELD,

end of ty_field_itab.

• in the private section of another class

data: field_itab type table of ty_field_itab.

*still in other class,

append field to fielditab.

Which gives an error! Cannot convert field to field of type fielditab.

Think I have to use create data?

thanks

Dylan.

Even better would be a vector type table, that can store and retrieve any

object.

Anyone has the code for that? Should be long, maybe even write a nice class around it.

thanks

Dylan.

Try to use around your code... (take out the spaces after and before the bracket though! )

Assuming the type in your first class is public. I'll call your first class CL1.

Types: begin of ty_field_itab,
         fld type ref to ZCL_BDC_FIELD,
        end of ty_field_itab.

in the private section of another class

data: field_itab type table of CL1=>ty_field_itab,
      _field like line of field_itab.
...
* _field gets filled...

*still in other class, 
append _field to field_itab. 

Re, your idea of a vector table... yes you can do it. Like this:

TYPES: BEGIN OF ty_vector_entry,
       hdr TYPE ...some kind of header structure...
       ref TYPE REF TO DATA,
       END OF ty_vector,
     ty_vector TYPE STANDARD/SORTED/HASHED TABLE OF ty_vector_entry ... key defn.

DATA: l_entry TYPE ty_vector_entry,
      lt_vector TYPE ty_vector.
...
my_obj1 TYPE REF TO CL1,
* populate the l_entry-hdr appropriately
GET REFERENCE OF my_obj1 into l_entry-ref.
INSERT l_entry INTO TABLE lt_vector.

my_obj2 TYPE REF TO CL2,
* populate the l_entry-hdr appropriately
GET REFERENCE OF my_obj2 into l_entry-ref.
INSERT l_entry INTO TABLE lt_vector.

my_data TYPE string,
* populate the l_entry-hdr appropriately
GET REFERENCE OF my_data into l_entry-ref.
INSERT l_entry INTO TABLE lt_vector.
