------------------------------------------------
Summary: Simpler XMI writing than XWriter
Key: UIMA-3219
URL: https://issues.apache.org/jira/browse/UIMA-3219
Project: UIMA
Issue Type: Improvement
Components: uimaFIT
Reporter: Steven Bethard
Assignee: Richard Eckart de Castilho
Fix For: 2.0.0uimaFIT
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:
{noformat}
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();
}
}
}
{noformat}
(The new XUtil class could also grow methods for writing XCAS, and for reading
XMI and XCAS.)
