    • CONNECTION_SYMBOL

      @Deprecated public static final org.apache.jena.sparql.util.Symbol CONNECTION_SYMBOL
      Deprecated.
      Symbol for placing a connection (TODO supplier?) into an arq context

    • symRdfDataSource

      public static final org.apache.jena.sparql.util.Symbol symRdfDataSource
      A data source for making sub-sparql queries. Care needs to be taken to avoid deadlocks: If the original connection is in a write transaction, then sub-queries may block.

    • enableRelativeIrisInQueryResults

      public static org.apache.jena.rdflink.RDFLink enableRelativeIrisInQueryResults(org.apache.jena.rdflink.RDFLink delegate)

      Parameters:
      conn -
