Class UnionExpression

java.lang.Object
org.topbraid.shacl.expr.AbstractNodeExpression
org.topbraid.shacl.expr.ComplexNodeExpression
org.topbraid.shacl.expr.lib.UnionExpression
All Implemented Interfaces:
NodeExpression
public class UnionExpression extends ComplexNodeExpression

  • Constructor Details

    • UnionExpression

      public UnionExpression(org.apache.jena.rdf.model.RDFNode expr, List<NodeExpression> inputs)

  • Method Details

    • eval

      public org.apache.jena.util.iterator.ExtendedIterator<org.apache.jena.rdf.model.RDFNode> eval(org.apache.jena.rdf.model.RDFNode focusNode, NodeExpressionContext context)
      Description copied from interface: NodeExpression
      Produces an iterator of value nodes for a given focus node.
      Parameters:
      focusNode - the focus node
      context - the context
      Returns:
      an iterator (never null)

    • getFunctionalSyntaxArguments

      public List<String> getFunctionalSyntaxArguments()
      Specified by:
      getFunctionalSyntaxArguments in class ComplexNodeExpression

    • getInputExpressions

      public List<NodeExpression> getInputExpressions()
      Specified by:
      getInputExpressions in interface NodeExpression
      Overrides:
      getInputExpressions in class AbstractNodeExpression

    • getOutputShape

      public org.apache.jena.rdf.model.Resource getOutputShape(org.apache.jena.rdf.model.Resource contextShape)
      Description copied from interface: NodeExpression
      Gets the shape of the output data (if known), based on a context shape. For example, for a path expression it would try to infer the output shape from the sh:class or sh:node of the property (path).
      Specified by:
      getOutputShape in interface NodeExpression
      Overrides:
      getOutputShape in class AbstractNodeExpression
      Parameters:
      contextShape - the shape where the evaluation would start, e.g. the node shape of the sh:values statement
      Returns:
      an output shape or null if unknown

    • getTypeId

      public String getTypeId()

    • visit

      public void visit(NodeExpressionVisitor visitor)
