QueryExecOverRowSet

public QueryExecOverRowSet(org.apache.jena.query.Query query)

Method Details

createRowSet

protected abstract org.apache.jena.sparql.exec.RowSet createRowSet(org.apache.jena.query.Query selectQuery)

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.

doSelect

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

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.
