SparqlParserListener

It is possible to add listeners to the SPARQLParser to be fired for weel-formed or malformed requests.

Interface methods

The SparqlParserListener interface has two methods:

• The SparqlParserListener.emitWellformedRequest(String sparqlQuery, SPARQLRequest request) will be called for a well-formed request
• The SparqlParserListener.emitException(String sparqlQuery, SPARQLRequest request, MalformedQueryException ex) will be called for a not well-formed request

Adding a listener

Two methods allow to add a listener to the parser:

• The SPARQLParserFactory.addSparqlParserListener(SparqlParserListener listener) adds a listener to all parsers created by the factory
• The SparqlParser.addSparqlParserListener(SparqlParserListener listener) adds a listener to the parser
