Hi,
we are using version 2.2.3 of org.eclipse.xsd at the moment in order to
preserve compatibility wit java 1.4.x.
We are producing maps mapping elemDeclNames to the corresponding
org.eclipse.xsd.impl.XSDParticleImpl$XSDNFA automata to access them in
order to satisfy queries.
Is there a way to serialize such maps in order to create cached copy of
the rules and avoid each time their building?
We are obtaining the following exception while serializing:
Error saving rules map org.eclipse.xsd.impl.XSDParticleImpl$XSDNFA
java.io.NotSerializableException:
org.eclipse.xsd.impl.XSDParticleImpl$XSDNFA
at
java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.j ava:1059).....
I've seen that in the JavaDoc of previous versions of the library, i.e.
2.1.1 the Serializable interface was implemented.
Class org.eclipse.xsd.impl.XSDParticleImpl extends
XSDComplexTypeContentImpl implements Serializable
Has the modality of serialization been changed? Is there a different way
to obtain the same result?
Thanks in advance for any hint
Tommaso

Tommaso,
I've recently made improvements to the speed of creating an the DFAs:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=200848
But I don't think we've ever supported java.io.Serializeable for XSD
instances. You can serialize a reference to any EObject using
EcoreUtil.getURI(eObject) and it can be resolved using
ResourceSet.getEObject(uri, true) so if you want to serialize
information needed to rebuild the map itself you could use that type of
approach.
