I have just tried recasting the question; basically Callable has no
ability to report on progress; the goal is only to stop the Callable
using a Future. The following adapter does this just fine ...
public static Callable<Map<String,Object>> callable( String name,
Map<String,Object> input ){
final Process process = process( name, input );
return new Callable<Map<String,Object>>(){
public Map<String, Object> call() throws Exception {
process.process( new ThreadProgressListener() );
return process.getResult();
}
};
}
Where:
public class ThreadProgressListener extends NullProgressListener {
public boolean isCanceled() {
return Thread.currentThread().isInterrupted();
}
}
Is this sufficient for your needs Martin? I am sorry but we have the
hard and fast requirement to report on Progress as it happens (both for
the Eclipse Jobs API and for the the WPS specification).
