Interface DataCodec

All Known Implementing Classes:
ProtoDataCodec
public interface DataCodec
Strategy interface for encoding and decoding business data.

Provides methods to serialize objects to byte[] and deserialize byte[] back to typed objects. Default convenience methods handle primitive wrappers (IntValue, LongValue, BoolValue, StringValue) and list wrappers (IntValueList, LongValueList, BoolValueList, StringValueList, ByteValueList) transparently.
