Class NodeShape

java.lang.Object

org.eclipse.rdf4j.sail.shacl.AST.NodeShape

All Implemented Interfaces:

PlanGenerator, QueryGenerator, RequiresEvalutation

Direct Known Subclasses:

TargetClass, TargetNode

public class NodeShape
extends Object
implements PlanGenerator, RequiresEvalutation, QueryGenerator

The AST (Abstract Syntax Tree) node that represents the NodeShape node. NodeShape nodes can have multiple property nodeShapes, which are the restrictions for everything that matches the NodeShape.
