AutoCloseable, org.aksw.jenax.dataaccess.sparql.execution.query.QueryExecutionWrapper, org.apache.jena.query.QueryExecution
public class QueryExecutionTimeoutExogeneous extends org.aksw.jenax.dataaccess.sparql.execution.query.QueryExecutionWrapperBase<org.apache.jena.query.QueryExecution>
Query execution that applies a timeout "from the outside" (= exogeneous). Upon query execution, a new thread is created that calls .abort() on the underlying query execution once the timeout is reached.
