Description
Serialization of Data Objects to a String xmlstr Using the
Identical Transformation ID A date field date,
a time field time, and a data reference variable dref1
are serialized. The data reference variable points to an anonymous object reference variable, which
in turn points to an object of the class c2. Objects serialized in this way can be stored persistently, for example in a
data cluster. After the
objects are imported from where they are stored, they are deserialized to further data objects. Following
deserialization, dref2 points to another anonymous reference variable, such as dref1. This
anonymous data object
and the instance of the class c2 to which it points are generated during the deserialization.
The XML document generated in the serialization is in
asXML format. It is displayed
in a browser and has approximately the content described below. In this description, line breaks and
indents have been added. The element values contains the asXML representations
of the three passed data objects. In the names X-MLDAT and X-MLTIM,
"xml" is replaced by "X-ML". The attribute
href of the element REF uses the key "d1" to refer to the representation of the associated
anonymous data object
in the element heap. This uses the key "o3"
to refer to the representation of the instance of the class c2, which is
also in the element heap. This representation is divided into the object
parts for the classes c1 and c2. The object part
for c1 contains the representation of the double-row structured internal
table carriers. The object part for c2 contains the representation for the output parameter count of the method SERIALIZE_HELPER.
