Interface RedisSerializer<T>

All Known Implementing Classes:

GenericJackson2JsonRedisSerializer, GenericToStringSerializer, Jackson2JsonRedisSerializer, JdkSerializationRedisSerializer, OxmSerializer, StringRedisSerializer

public interface RedisSerializer<T>

Basic interface serialization and deserialization of Objects to byte arrays (binary data). It is recommended that implementations are designed to handle null objects/empty arrays on serialization and deserialization side. Note that Redis does not accept null keys or values but can return null replies (for non existing keys).
