Class SPARQLExecutor

java.lang.Object

org.aksw.qa.commons.utils.SPARQLExecutor

public class SPARQLExecutor
extends Object

In qa.commons, there are 2 differnet ways to fire queries to an endpoint, SPARQL and this class. This becomes tedious to keep clean, especially when both share the same (hardcopied) code. Please consider merging the functionality in favor of SPARQL or ThreadedSPARQL
