Class BasicStringTypeAdapter<T>

java.lang.Object

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

All Implemented Interfaces:

JsonTypeAdapter<T>

Direct Known Subclasses:

LocalDateTimeTypeAdapter, LocalDateTypeAdapter

public abstract class BasicStringTypeAdapter<T>
extends Object
implements JsonTypeAdapter<T>

Convenient abstract implementation of JsonTypeAdapter. Extend it if you need to represent unwrap (T) 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 LocalDateTimeTypeAdapter.
