Description
Mark Paluch opened DATACASS-283 and commented
The Cassandra 3 Java driver provides a CodecRegistry which allows the usage of custom codecs for object and UDT value mapping. The mapper is an additional artifact which could be added optionally to the classpath.
@UDT(name = "address")
public class Address { ... }
codec = AnnotationParser.parseUDT(mappedClass, ReflectionMapper.factory(), this);
session.getCluster().getConfiguration().getCodecRegistry().register(codec);
Row row = session.execute("select address from user where id = 1").one();
Address address = row.get("address", Address.class);
