Example 21 with Context

use of org.apache.jena.sparql.util.Context in project jena by apache.

Example 22 with Context

use of org.apache.jena.sparql.util.Context in project jena by apache.

the class TDB method wireIntoExecution.

private static void wireIntoExecution() {
    // Globally change the stage generator to intercept BGP on TDB
    Context cxt = ARQ.getContext();
    StageGenerator orig = StageBuilder.chooseStageGenerator(cxt);
    // Wire in the TDB stage generator which will make TDB work whether
    // or not the TDB executor is used. This means that datasets of mixed
    // graph types inside a general purpose dataset work.
