use of io.trino.type.TypeSignatureDeserializer in project trino by trinodb.

the class TestSignature method testSerializationRoundTrip.

@Test
public void testSerializationRoundTrip() {
    ObjectMapperProvider objectMapperProvider = new ObjectMapperProvider();
    objectMapperProvider.setJsonDeserializers(ImmutableMap.of(Type.class, new TypeDeserializer(TESTING_TYPE_MANAGER), TypeSignature.class, new TypeSignatureDeserializer()));
    JsonCodec<Signature> codec = new JsonCodecFactory(objectMapperProvider, true).jsonCodec(Signature.class);
    Signature expected = new Signature("function", BIGINT.getTypeSignature(), ImmutableList.of(BOOLEAN.getTypeSignature(), DOUBLE.getTypeSignature(), VARCHAR.getTypeSignature()));
    String json = codec.toJson(expected);
    Signature actual = codec.fromJson(json);
    assertEquals(actual.getName(), expected.getName());
    assertEquals(actual.getReturnType(), expected.getReturnType());
    assertEquals(actual.getArgumentTypes(), expected.getArgumentTypes());
