Examples with NoneSingleRel org.apache.calcite.plan.volcano.PlannerTests.NoneSingleRel used on opensource projects

Example 1 with NoneSingleRel

use of org.apache.calcite.plan.volcano.PlannerTests.NoneSingleRel in project calcite by apache.

the class VolcanoPlannerTest method testRemoveSingleReformed.

/**
 * Previously, this didn't work because ReformedRemoveSingleRule uses a
 * pattern which spans calling conventions.
 */
// broken, because ReformedSingleRule matches child traits strictly
@Ignore
@Test
public void testRemoveSingleReformed() {
    VolcanoPlanner planner = new VolcanoPlanner();

    planner.addRelTraitDef(ConventionTraitDef.INSTANCE);
    planner.addRule(new PhysLeafRule());
    planner.addRule(new ReformedRemoveSingleRule());
    RelOptCluster cluster = newCluster(planner);
    NoneLeafRel leafRel = new NoneLeafRel(cluster, "a");
    NoneSingleRel singleRel = new NoneSingleRel(cluster, leafRel);

    assertTrue(result instanceof PhysLeafRel);
    PhysLeafRel resultLeaf = (PhysLeafRel) result;

Example 2 with NoneSingleRel

use of org.apache.calcite.plan.volcano.PlannerTests.NoneSingleRel in project calcite by apache.

the class VolcanoPlannerTest method testTransformSingleReformed.

 * this one didn't work due to the definition of ReformedSingleRule.

Example 3 with NoneSingleRel

use of org.apache.calcite.plan.volcano.PlannerTests.NoneSingleRel in project calcite by apache.
