Get changes

The following example shows you how to get added and updated items (files / folders). It is possible to specify time range to get changes after/before specified time.
import java.util.List;

import com.independentsoft.share.Change;
import com.independentsoft.share.ChangeItem;
import com.independentsoft.share.ChangeQuery;
import com.independentsoft.share.Service;
import com.independentsoft.share.ServiceException;

            query.setAdd(true);
            query.setUpdate(true);
            query.setItem(true);
