the class AnalyzerTracker method addingService.

@Override
public TrackingStruct addingService(ServiceReference<ResourceAnalyzer> reference) {
    TrackingStruct struct = new TrackingStruct();
    try {
        String filterStr = (String) reference.getProperty(ResourceAnalyzer.FILTER);
        Filter filter = (filterStr != null) ? FrameworkUtil.createFilter(filterStr) : null;

    }
    return struct;
}
