示例1: UniqueEngineBuilder

TEST_F(TableTupleTest, ComputeNonInlinedMemory)
{
    UniqueEngine engine = UniqueEngineBuilder().build();
    Pool *pool = ExecutorContext::getTempStringPool();

    // Make sure that inlined strings are actually inlined
    int32_t maxInlinableLength = UNINLINEABLE_OBJECT_LENGTH/MAX_BYTES_PER_UTF8_CHARACTER - 1;
    ScopedTupleSchema allInlineSchema{Tools::buildSchema(VALUE_TYPE_BIGINT,
                                                         std::make_pair(VALUE_TYPE_VARCHAR, maxInlinableLength))};
    PoolBackedTupleStorage tupleStorage;
    tupleStorage.init(allInlineSchema.get(), pool);
    tupleStorage.allocateActiveTuple();
    TableTuple inlineTuple = tupleStorage;

    Tools::setTupleValues(&inlineTuple, int64_t(0), "dude");
    EXPECT_EQ(0, inlineTuple.getNonInlinedMemorySizeForPersistentTable());

    // Now check that an non-inlined schema returns the right thing.
    int32_t nonInlinableLength = UNINLINEABLE_OBJECT_LENGTH + 10000;
    ScopedTupleSchema nonInlinedSchema{Tools::buildSchema(VALUE_TYPE_BIGINT,
                                                         std::make_pair(VALUE_TYPE_VARCHAR, nonInlinableLength))};
    tupleStorage.init(nonInlinedSchema.get(), pool);
    tupleStorage.allocateActiveTuple();
    TableTuple nonInlinedTuple = tupleStorage;

    NValue nonInlinedString = Tools::nvalueFromNative("123456");
    Tools::setTupleValues(&nonInlinedTuple, int64_t(0), nonInlinedString);
    EXPECT_EQ(nonInlinedString.getAllocationSizeForObjectInPersistentStorage(),
              nonInlinedTuple.getNonInlinedMemorySizeForPersistentTable());
