Major Description
Add more logging to TraceComponent.java, for the following:
- NormalizedMassage.getPropertyNames(): get the objects in some string format.
- If NormalizedMassage.getProperty() is of type javax.xml.transform.Source, convert the type of a String for logging
See below code for possible example:
/**
* Outputs the properties on the {@link NormalizedMessage}. Properties of
* type {@link Source} are transformed to a {@link String} before
* being output.
*
* @param message The {@link NormalizedMessage} to be processed
*/
@SuppressWarnings("unchecked")
protected void outputProperties(NormalizedMessage message) {
// Loop over all the properties on the normalized message
for (Object o : message.getPropertyNames()) {
// NormalizedMessage API does not use generics. This interface is
// written in Java older than 5.0. On the basis of other methods and
// the default implementation of this interface we can assume that
// only String keys are allowed.
String key = (String) o;
try {
Object contents = message.getProperty(key);
// Is this the only value type that we would like to treat
// differently? The default behavior is to invoke toString() on
// the object.
if (contents instanceof Source) {
contents = getSourceTransformer().toString((Source) contents);
}
log.info("Value for property '" + key + "' is: " + contents);
} catch (TransformerException e) {
log.error("Failed to turn property '" + key + "' value into text: " + e, e);
}
}
