use of io.prestosql.operator.aggregation.state.NullableLongState in project hetu-core by openlookeng.

the class TestStateCompiler method testPrimitiveNullableLongSerialization.

@Test

    AccumulatorStateFactory<NullableLongState> factory = StateCompiler.generateStateFactory(NullableLongState.class);
    AccumulatorStateSerializer<NullableLongState> serializer = StateCompiler.generateStateSerializer(NullableLongState.class);
    NullableLongState state = factory.createSingleState();
    NullableLongState deserializedState = factory.createSingleState();
    state.setLong(2);
    state.setNull(false);
    BlockBuilder builder = BIGINT.createBlockBuilder(null, 2);
    serializer.serialize(state, builder);
    state.setNull(true);
    serializer.serialize(state, builder);
    Block block = builder.build();
    assertEquals(block.isNull(0), false);
    assertEquals(BIGINT.getLong(block, 0), state.getLong());
    serializer.deserialize(block, 0, deserializedState);
    assertEquals(deserializedState.getLong(), state.getLong());
    assertEquals(block.isNull(1), true);
