handleClose

protected void handleClose()
                    throws QueryEvaluationException

Deprecated.

Overrides:

handleClose in class org.eclipse.rdf4j.common.iteration.IterationWrapper<org.eclipse.rdf4j.model.Statement,QueryEvaluationException>

Throws:

QueryEvaluationException

run

public void run()

Deprecated.

Specified by:

run in interface Runnable

startRDF

public void startRDF()
              throws RDFHandlerException

Deprecated.

Specified by:

startRDF in interface RDFHandler

Throws:

RDFHandlerException

getNamespaces

public Map<String,String> getNamespaces()

Deprecated.

Description copied from interface: GraphQueryResult

Retrieves relevant namespaces from the query result.
The contents of the Map may be modified after it is returned, as the initial return may be performed when the first RDF Statement is encountered.

Specified by:

getNamespaces in interface GraphQueryResult

Returns:

a Map<String, String> object containing (prefix, namespace) pairs.
