Hi,
is there a way to get object-IDs (for the "identity" attribute) automatically
generated by Castor for XML (!) binding. I noticed the key-generator feature for JDO,
but did not manage to get it working for marshalling to XML.
I am currently using the "identity & reference"-feature of Castor to manage the
serialization of potential circular object-trees with multi-references. Therefore - as
I have understood - we need to provide unique IDs for each object. By now, I create
those IDs manually with the help of getId() and setId() methods for each of my
serializable objects. But I believe that this can't be the preferred way!?!
Here is my mapping file, where the "key-generator" attribute seems to be ignored:
<?xml version="1.0"?>
<mapping>
<description>Castor-Mapping</description>
<class name="ClassA" identity="id" key-generator="MAX" auto-complete="true">
<map-to xml="ClassA"/>
<field name="id" type="string">
<xml name="id" node="attribute"/>
</field>
<field name="val" type="ClassA">
<bind-xml name="val" node="element" reference="true"/>
</field>
</class>
<class name="ContainerA">
<map-to xml="ContainerA"/>
<field name="vec" type="ClassA" collection="vector">
</field>
</class>
<class name="ContainerB">
<map-to xml="ContainerB"/>
<field name="vec" type="ClassA" collection="vector">
<bind-xml name="vec" node="element" reference="true"/>
</field>
</class>
</mapping>
If there is a more elegant way, I would appreciate any hints and helpful code samples
(especially how to change the mapping file).
