Examples of org.openjena.riot.ErrorHandler

org.openjena.riot.ErrorHandler
An Error handler captures the policy for dealing with warnings, errors and fatal errors. Fatal errors mean termination of processing and must throw a RiotException. Errors and warnings may throw an exception to terminate processing or may return after, for example, logging a message. The exact policy is determined the error handler itself.

            
        in = new FileInputStream("data.trig") ;
        LangRIOT parser = RiotReader.createParserQuads(in, Lang.TRIG, "http://example/base", noWhere) ;
        
        // Parser to first error or warning.
        ErrorHandler errHandler = ErrorHandlerFactory.errorHandlerStrict ;


        // Now enable stricter checking, even N-TRIPLES must have absolute URIs. 
        ParserProfile profile = RiotLib.profile(baseURI, true, true, errHandler) ;


        // Just set the error handler.
