ST - Access to ABAP Objects from ST
Classes and objects in ABAP objects can be accessed as follows in
ST
programs:
tt:call-method , call static
methods
tt:call-method , call instance
methods
tt:create-object , create objects
Data roots, parameters, and variables can all be bound to the interface
parameters at the same time.
Calling methods also allows access to the current XML stream.
tt:call-method ,
writer , reader
Note
When you bind data nodes, you must remember that the content of a data
root cannot be modified by serialization; only write access is possible
to a data root during deserialization. This places a strong restriction
on the use of data nodes as actual parameters. Since parameters and
attributes for general use cannot be serialized or deserialized (unless
they contain an elementary value), methods called from ST
programs are mainly suited for editing elementary values (for example,
for conversions). You can circumvent this restriction by accessing an
ABAP data object bound to a data root in the called method.
