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 Detail

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 Detail

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
