doSelect

protected org.apache.jena.sparql.exec.QueryExec doSelect(org.apache.jena.query.Query selectQuery)

Description copied from class: QueryExecBaseSelect

The actual method that needs to be implemented. The argument is always a SPARQL query of select type. The RowSet may need to implement close() in order to close an underlying query execution.
