Description
The whole FileNamer thing in XWriter is more complexity than most users need. You have to declare a new FileNamer class every time you create an XWriter. But that FileNamer class, even though it takes a JCas just like an annotator would, isn't actually an annotator, it's a totally different API.
We should instead leverage our users' existing understanding of the annotator API. If they're going to have to write a new class every time, we should let them write an annotator class like they're already used to. We should provide a simple static method that makes it easy to write such a class, something like:
public class XUtil {
public static void writeXMI(JCas jCas, File outputFile) throws IOException, SAXException {
FileOutputStream outputStream = new FileOutputStream(outputFile);
try {
ContentHandler handler = new XMLSerializer(outputStream).getContentHandler();
XmiCasSerializer serializer = new XmiCasSerializer(jCas.getTypeSystem());
serializer.serialize(jCas.getCas(), handler);
}
finally {
outputStream.close();
}
}
}
(The new XUtil class could also grow methods for writing XCAS, and for reading XMI and XCAS.)
