Schlagwort: convert_struc

Variante 1 (FIELD-SYMBOLS, CASTING: Struktur <-> Typ x)

* einfachen Typ deklarieren
TYPES: BEGIN OF ty_struct,
         matnr TYPE matnr,
         int   TYPE i,
         float TYPE f,
         text  TYPE char10,
       END OF ty_struct.

* Feldsymbol für Binärdaten
FIELD-SYMBOLS <x> TYPE x.
* Feldsymbol für Strukturdaten
FIELD-SYMBOLS <s> TYPE ty_struct.

* Struktur anlegen, deren Daten kovertiert werden soll
DATA(lv_s) = VALUE ty_struct( matnr = '1234567890'
                              int   = 1
                              float = '1.1'
                              text  = 'abc' ).

* Struktur in Binärdaten umwandeln
ASSIGN lv_s TO <x> CASTING.
IF <x> IS ASSIGNED.
* Binärdaten in Struktur umwandeln
  ASSIGN <x> TO <s> CASTING.
  IF <s> IS ASSIGNED.
    DATA(lv_s2) = <s>.
* Datenausgabe
    WRITE: / lv_s2-matnr.
    WRITE: / lv_s2-int.
    WRITE: / lv_s2-float.
    WRITE: / lv_s2-text.
  ENDIF.
ENDIF.

Variante 2 (xstring -> Struktur)

* https://www.consolut.com/s/sap-ides-zugriff/d/e/doc/M-CL_ABAP_CONV_IN_CE/
* einfachen Typ deklarieren
TYPES: BEGIN OF ty_struct,
         text TYPE char5,
         int  TYPE i,
       END OF ty_struct.

* Zielstruktur
DATA(lv_s) = VALUE ty_struct( ).

* Konverterobjekt mit UTF-8 und Little Endian Konvertierung
DATA(o_conv) = cl_abap_conv_in_ce=>create( encoding = 'UTF-8' endian = 'L' ).
* View-Objekt
DATA(o_view) = cl_abap_view_offlen=>create_legacy_view( lv_s ).
* Eingabepuffer mit Binärdaten
DATA(lv_buffer) = CONV xstring( '616263202000000005000000' ).

* Konvertierung xstring -> Struct
*  in: HEX: 616263202000000005000000
* out: Struct: text: abc
*               ínt: 5
o_conv->convert_struc( EXPORTING
                         input = lv_buffer
                         view  = o_view
                       IMPORTING
                         data  = lv_s ).

* Datenausgabe
WRITE: / lv_s-text.
WRITE: / lv_s-int.

Variante 3 (Struktur -> xstring)

* https://www.consolut.com/s/sap-ides-zugriff/d/e/doc/M-CL_ABAP_CONV_OUT_CE/
* einfachen Typ deklarieren
TYPES: BEGIN OF ty_struct,
         text TYPE char5,
         int  TYPE i,
       END OF ty_struct.

* Struktur mit Quelldaten
DATA(lv_s) = VALUE ty_struct( text = 'abc'
                              int  = 5 ).

* Konverterobjekt mit UTF-8 und Little Endian Konvertierung
DATA(o_conv) = cl_abap_conv_out_ce=>create( encoding = 'UTF-8' endian = 'L' ).
* View-Objekt
DATA(o_view) = cl_abap_view_offlen=>create_legacy_view( lv_s ).
* Ausgabepuffer für Binärdaten
DATA: lv_buffer type xstring.

* Konvertierung Struct -> xstring
*  in: Struct: text: abc
*               ínt: 5
* out: HEX: 616263202000000005000000
o_conv->convert_struc( EXPORTING
                         data   = lv_s

                       IMPORTING
                         buffer = lv_buffer ).

* Datenausgabe
WRITE: / lv_buffer.
