Class Checker

java.lang.Object

org.apache.jena.riot.system.Checker

public class Checker
extends java.lang.Object

Functions for checking nodes, triples and quads.

If the errorHandler is null, use the system wide handler.

If the errorHandler line/columns numbers are -1, -1, messages do not include them.

Operations "checkXXX(item)" are for boolean testing and do not generate output.

iriViolations

public static void iriViolations(org.apache.jena.iri.IRI iri)

Process violations on an IRI Calls the ErrorHandler on all errors and warnings (as warnings).
