      public static org.apache.jena.sparql.engine.QueryIterator execService(org.apache.jena.sparql.engine.binding.Binding binding, org.apache.jena.sparql.engine.ExecutionContext execCxt, org.apache.jena.sparql.algebra.op.OpService opService, org.apache.jena.rdfconnection.RDFConnection target, boolean isStreamingAllowed, boolean applyDatasetDescription)
      Runs an OpService on the given connection. Resulting bindings must be compatible with the given one and will be merged with it.
      Parameters:
      binding - The parent binding that is merged with the bindings obtained from the execution.
      execCxt - The execution context
      opService - The service operation to delegate to the RDFConnection. Its serviceNode is ignored, but silent is repsected.
      isStreamingAllowed - If true then a live iterator over the result is returned. Otherwise the method materializes the data before returning. If opService.isSilent() is true then isStreaming has no effect because all data must be materialized first in order to detect errors.
      applyDatasetDescription - If true, then check if the execCxt's datasat is a DynamicDatasets and apply its default and named graph IRIs to the generated query.

    • execService

      public static org.apache.jena.sparql.engine.QueryIterator execService(org.apache.jena.sparql.algebra.op.OpService opService, org.apache.jena.rdfconnection.RDFConnection target, boolean isStreamingAllowed, org.apache.jena.sparql.core.DatasetDescription datasetDescription)
      Runs an OpService on the given connection. Ignores the service IRI but considers the silent flag.

    • exec

      public static org.apache.jena.sparql.engine.QueryIterator exec(org.apache.jena.sparql.exec.QueryExecBuilder builder, boolean isSilent, boolean isStreamingAllowed)
      Obtain a RowSet from the given queryExecBuilder. The RowSet is materialized when the silent flag is set or streaming is disallowed. Otherwise it is streamed.
