  org.eaglei.datatools.etl.utils.DeETL

public class DeETL
extends java.lang.Object

This class is for deleting instances which ETled from particular file, -f takes filename as input ,this is the file name which we want to delete all instances ETLed from .-r takes repository configuration file path FLOW : deleteInsntaceETledFromFIle(String) takes file name as input ,it then calls getResourcesOfFile(String) where it builds query to ge the Instance URI's we want to delete,It builds the query by calling SPARQLQueryUtil.getInstance().getResourcesETLedFromFileQuery(fileName); .We query repository using the query which we built it then returns results in xml format ,xml is parsed for Instance URIs in ETLSPARQLQueryUtil.getInstanceURI(resources) method ,which returns array if instance URI's . instanceURI array is then passed to deleteInsntaceETledFromFIle(String) where it will be deleted one by one by looping throught he array
