use of com.apple.foundationdb.tuple.ByteArrayUtil in project fdb-record-layer by FoundationDB.

the class BunchedTupleSerializerTest method serializeKey.

@Test
public void serializeKey() {
    List<Tuple> sortedTuples = TEST_TUPLES.stream().sorted().collect(Collectors.toList());
    List<Tuple> sortedKeys = TEST_TUPLES.stream().map(serializer::serializeKey).sorted(ByteArrayUtil::compareUnsigned).map(serializer::deserializeKey).collect(Collectors.toList());
    assertEquals(sortedTuples, sortedKeys);
    // Add a subspace and make sure unpacking by length works.
    Subspace subspace = new Subspace(Tuple.from("fake", "subspace"));
    List<Tuple> prefixedTuples = TEST_TUPLES.stream().map(serializer::serializeKey).map(b -> ByteArrayUtil.join(subspace.getKey(), b)).map(data -> serializer.deserializeKey(data, subspace.getKey().length)).collect(Collectors.toList());
    assertEquals(TEST_TUPLES, prefixedTuples);
