Examples of QueryExecutor

org.deri.grefine.reconcile.rdf.executors.QueryExecutor
@author fadmaathis interface takes care of executing SPARQL queries. the RDF to query might be a dump or a remote SPARQL endpoint. different implementation should take care of this.
org.mongolink.domain.query.QueryExecutor
org.mule.module.db.internal.domain.executor.QueryExecutor
Executes queries against a database
