Class GraphValidation

java.lang.Object

org.apache.jena.shacl.GraphValidation

public class GraphValidation
extends Object

Operations to work on graph with SHACL. Example: update with possible exception:

      Shapes shapes = ...
      try {
        GraphValidation.updateEx(shapes, graph, ()->{
            ... application code ...
        });
     } catch (ShaclValidationException ex) {
           ShLib.printReport(ex.getReport());
     }
 

If validation fails, the transaction is aborted. Example: update with report:

     Shapes shapes = ...
     ValidationReport report = GraphValidation.updateEx(shapes, graph, ()->{
         ... application code ...
     });
     if ( ! report.conforms() ) {
        // Update aborted.
        ShLib.printReport(report);
     }
 

Example: update regardless and then report:

     Shapes shapes = ...
     ... graph changes ...
     ValidationReport report = ShaclValidation.validate(shapes, graph);
     if ( ! report.conforms() ) {
        // Changes happened.
        ShLib.printReport(report);
     }

updateAndReport

public static ValidationReport updateAndReport(Shapes shapes,
                                               Graph data,
                                               Runnable update)

Update the graph. This operation aborts and throws a ShaclValidationException if there are any validation results from shapes (of any severity). If the update results in a valid graph, return without exception (with a ValidationReport with ValidationReport.conforms returning true).
