Class QueryExecutionFactory

java.lang.Object

org.apache.jena.query.QueryExecutionFactory

public class QueryExecutionFactory
extends java.lang.Object

QueryExecutionFactory provides some convenience operations for making QueryExecution objects. It is not comprehensive and only covers common, simple cases.

For more control of building a local or remote QueryExecution object see the builder pattern:

• QueryExecution.create(). ... .build() for querying local data.
• QueryExecutionHTTP.service(url). ... .build() for querying a remote store using HTTP.

See also RDFConnection for working with SPARQL Query, SPARQL Update and SPARQL Graph Store Protocol together.
