org.xmlBlaster.contrib.dbwatcher.detector.I_ChangeDetector.checkAgain()
Check the observed data for changes. @param attrMap This map can be null. The event source can transportsome specific information to help the changeDetector doing its work efficiently. @return > 0 if the observed data has changed. If supported by the pluginthe the number of changed rows, @throws Exception Can be of any type
