Package org.javers.core.json

Class BasicStringTypeAdapter<T>

java.lang.Object

org.javers.core.json.JsonTypeAdapterTemplate<T>

org.javers.core.json.BasicStringTypeAdapter<T>

All Implemented Interfaces:

JsonTypeAdapter<T>

public abstract class BasicStringTypeAdapter<T>
extends JsonTypeAdapterTemplate<T>

Convenient abstract implementation of JsonTypeAdapter. Extend it if you need to represent your ValueType as single String and don't want to deal with Gson API.

Implementation shouldn't take care about nulls (nulls are handled by Gson engine)

For concrete class example see org.javers.core.json.typeadapter.util.LocalDateTimeTypeAdapter.
