Class ShapesGraph

java.lang.Object
org.topbraid.shacl.engine.ShapesGraph
public class ShapesGraph extends Object
Represents a shapes graph as input to an engine (e.g. validation or inferencing). This is basically a collection of Shapes with some data structures that avoid repetitive computation.

  • Constructor Details

    • ShapesGraph

      public ShapesGraph(org.apache.jena.rdf.model.Model shapesModel)
      Constructs a new ShapesGraph. This should not be called directly, only from ShapesGraphFactory.
      Parameters:
      shapesModel - the Model containing the shape definitions

  • Method Details

    • clone

      public ShapesGraph clone()
      Overrides:
      clone in class Object

    • createConstraint

      public Constraint createConstraint(Shape shape, SHConstraintComponent component, List<SHParameter> params, org.apache.jena.rdf.model.RDFNode parameterValue)

    • getComponentWithParameter

      public SHConstraintComponent getComponentWithParameter(org.apache.jena.rdf.model.Property parameter)

    • getFastPrefixMapping

      public org.apache.jena.shared.PrefixMapping getFastPrefixMapping()

    • getPathString

      public String getPathString(org.apache.jena.rdf.model.Resource path)

    • getRootShapes

      public List<Shape> getRootShapes()
      Gets all non-deactivated shapes that declare a target and pass the provided filter.
      Returns:
      the root shapes

    • getShape

      public Shape getShape(org.apache.jena.graph.Node node)

    • getDefaultValueNodeExpressionsMap

      public Map<org.apache.jena.graph.Node,NodeExpression> getDefaultValueNodeExpressionsMap(org.apache.jena.rdf.model.Resource predicate)
      Gets a Map from (node) shapes to NodeExpressions derived from sh:defaultValue statements.
      Parameters:
      predicate - the predicate to infer
      Returns:
      a Map which is empty if the predicate is not mentioned in any inferences

    • getValuesNodeExpressionsMap

      public Map<org.apache.jena.graph.Node,NodeExpression> getValuesNodeExpressionsMap(org.apache.jena.rdf.model.Resource predicate)
      Gets a Map from (node) shapes to NodeExpressions derived from sh:values statements. Can be used to efficiently figure out how to infer the values of a given instance, based on the rdf:types of the instance.
      Parameters:
      predicate - the predicate to infer
      Returns:
      a Map which is empty if the predicate is not mentioned in any inferences

    • getShapesModel

      public org.apache.jena.rdf.model.Model getShapesModel()

    • isIgnored

      public boolean isIgnored(org.apache.jena.graph.Node shapeNode)

    • isIgnoredConstraint

      public boolean isIgnoredConstraint(Constraint constraint)

    • setConstraintFilter

      public void setConstraintFilter(Predicate<Constraint> value)
      Sets a filter Predicate that can be used to ignore certain constraints. See for example CoreConstraintFilter. Such filters must return true if the Constraint should be used, false to ignore. This method should be called immediately after the constructor only.
      Parameters:
      value - the new constraint filter

    • setShapeFilter

      public void setShapeFilter(Predicate<SHShape> value)
      Sets a filter Predicate that can be used to ignore certain shapes. Such filters must return true if the shape should be used, false to ignore. This method should be called immediately after the constructor only.
      Parameters:
      value - the new shape filter
