use of org.apache.druid.segment.vector.BaseFloatVectorValueSelector in project druid by druid-io.

the class CardinalityVectorAggregatorTest method testAggregateFloat.

    final CardinalityVectorAggregator aggregator = new CardinalityVectorAggregator(Collections.singletonList(new FloatCardinalityVectorProcessor(new BaseFloatVectorValueSelector(new NoFilterVectorOffset(values.length, 0, values.length)) {

        @Override
        public float[] getFloatVector() {
            return values;
        }

        @Nullable
        @Override
        public boolean[] getNullVector() {
            return nulls;
        }
    })));
    testAggregate(aggregator, values.length, NullHandling.replaceWithDefault() ? 4 : 3);
