Interface DataConverter

All Known Implementing Classes:
JacksonDataConverter
public interface DataConverter
Interface for serializing and deserializing data that gets passed to and from orchestrators and activities.

Implementations of this abstract class are free to use any serialization method. Currently, only strings are supported as the serialized representation of data. Byte array payloads and streams are not supported by this abstraction. Note that these methods all accept null values, in which case the return value should also be null.
