Hi people,
in my code I am dealing with a structure of a generic type, that means at design time I have no information about its particular components and their actual values. My aim is to serialize this structure into a string as fast as possible. All values of the components shall be separated by a certain delimiter. The kind of delimiter and the drawbacks of using delimiters in general shall not be discussed here.
My approach looks as follows:
The field symbol <ls_untyped_data> points to the generically-typed structure. lv_number_of_fields says how many components the structure has.
I use the approach of targeting to the component by its index, since this is faster according to the ABAP documentation than referring to the component name. If lv_counter equals 1, we are in the first loop cycle and simply add the value of the first component. If lv_Counter is > 1, we additionally add the field_separator.
lv_counter = 0.
DO lv_number_of_fields TIMES.
ADD 1 TO lv_counter.
ASSIGN COMPONENT lv_counter OF STRUCTURE <ls_untyped_data> TO <lv_field_value>.
IF lv_counter > 1.
mv_serialized_records = mv_serialized_records && lv_field_separator && <lv_field_value>.
ELSEIF lv_counter = 1.
mv_serialized_records = mv_serialized_records && <lv_field_value>.
ENDIF.
ENDDO.
This solution works as expected. However, when we deal with a large number of components (in a particular case I have more than 300) and we deal with a huge amount of structures (that means the entire coding above is called several times for a set of structures), this approach is considerably slow.
I suspect the reason is the dynamic lookup of the component at runtime. However, I am not aware of any other possibiltiy to dynamically inspect the structure.
Any suggestions?
Thanks!
