ST - Serialization and Deserialization
Serialization and deserialization is primarily based on following
schema:
In serializations, the literal elements of templates are passed to the
target XML data unchanged; the ST commands specified in
between are executed.
In deserializations, the source XML data is handled as an inbound
stream and compared to the template element by element. Elements (or
attributes or texts) of the inbound stream with the same name are
consumed if they are positioned in the ST program at the same
place or if a command is positioned there that can process the element.
After the successful comparison or consumption of the element, the
comparison of the subsequent element starts.
Serializations and deserializations can be divided into the following
topics:
Literal Template Content
Non-Literal Attributes
Namespaces
Transformation of ABAP Values
Value Assignments
Reading and Writing Variables
Flow Control
When a simple transformation is defined, note whether the serializations
and deserializations are symmetric .
Notes
In serializations and deserializations, the XML data is processed
in the form of writer streams and reader streams. When ABAP methods are
called from simple transformations, it is possible to
edit these XML streams .
Serializations and deserializations are subject to the general
restriction that the content of a data root
cannot be modified by serialization; only writes are possible to a data
root in deserializations.
