public class SparqlViewInstance extends ViewInstanceOld

  • Constructor Details

    • SparqlViewInstance

      public SparqlViewInstance(org.apache.jena.sparql.core.Quad queryQuad, org.apache.jena.sparql.core.Quad viewQuad, int instanceId, int subId, SparqlView parent, TwoWayBinding binding)

  • Method Details

    • copy

      public SparqlViewInstance copy()

    • getInstance

      public SparqlView getInstance()

    • getParent

      public SparqlView getParent()

    • getDefiningExpr

      public org.apache.jena.sparql.expr.Expr getDefiningExpr(org.apache.jena.sparql.core.Var var)
      For a view variable, return its defining SQL expression.
      Parameters:
      var -
      Returns:

    • getInferredDefiningExprs

      public List<org.apache.jena.sparql.expr.Expr> getInferredDefiningExprs(org.apache.jena.sparql.core.Var var)
      For a query variable, get all defining expressions, taking equivalences into account The question is, whether it makes sense to also treat constants as defining expressions. I guess yes, since a view quad such as ?s rdf:type ?o could be rewritten as ?s ?p ?o . with ?p = rdf:type
      Parameters:
      var -
      Returns:
