Example 6 with BitVector

use of org.apache.drill.exec.vector.BitVector in project drill by apache.

the class TestAllocators method testClearBitVector.

@Test
public void testClearBitVector() {
    final Properties props = new Properties() {

        {
            put(RootAllocatorFactory.TOP_LEVEL_MAX_ALLOC, "1000000");
        }
    };
    final DrillConfig config = DrillConfig.create(props);
    final BufferAllocator allc = RootAllocatorFactory.newRoot(config);
    final TypeProtos.MajorType.Builder builder = TypeProtos.MajorType.newBuilder();
    builder.setMinorType(TypeProtos.MinorType.BIT);
    builder.setMode(TypeProtos.DataMode.REQUIRED);
    final BitVector bv = new BitVector(MaterializedField.create("Field", builder.build()), allc);
    bv.getMutator().setValueCount(1);
    assertEquals(bv.getAccessor().getValueCount(), 1);
    bv.clear();
    assertEquals(bv.getAccessor().getValueCount(), 0);
