Hi,
I'm trying to convert an EnumMap object property to an implicit list,
but I can't seem to figure out how to skip the parent node in the
marshal method of the custom converter.
Example:
public class PIzza {
@XStreamConverter(ContentConverter.class)
protected EnumMap<ContentType, URI> content =
new EnumMap<ContentType, URI>(ContentType.class);
}
Desired XML:
<pizza>
<content type="text">content.txt</content>
<content type="html">content.html</content>
</pizza>
The key to attribute mapping is the reason I'm creating a custom converter.
Current converter:
public class ContentConverter implements Converter {
@Override
public void marshal(Object source, HierarchicalStreamWriter writer,
MarshallingContext context) {
EnumMap<Email.ContentType, URI> content =
(EnumMap<Email.ContentType, URI>) source;
for (Entry<Email.ContentType, URI> entry : content.entrySet()) {
writer.startNode("content");
writer.addAttribute("type",
entry.getKey().toString().toLowerCase());
context.convertAnother(entry.getValue());
writer.endNode();
}
}
}
Resulting XML:
<pizza>
<content>
<content type="text">content.txt</content>
<content type="html">content.html</content>
</content>
<pizza>
How do I prevent the parent "content" node from being created? Marking
the property as implicit causes the converter to be ignored, closing the
writer makes no difference and not starting new nodes will make a mess
of things.
It also makes me wonder how one has to unmarshal an implicit map, as the
entries won't be contained within a parent node any more.
Yours sincerely,
Age Bosma
