Interface ISparqlOrderBy
Interface for classes that represent SPARQL ORDER BY clauses.
Namespace: VDS.RDF.Query.Ordering
Assembly: dotNetRdf.dll
Syntax
public interface ISparqlOrderByRemarks
A SPARQL Order By clause provides a list of orderings, when parsed into the dotNetRDF model this is represented as a single ISparqlOrderBy for the first term in the clause chained to ISparqlOrderBy's for each subsequent term via the Child property.
Properties
