EnumJsonAdapter

class EnumJsonAdapter<T : Enum<T>?> : JsonAdapter<T>

A JsonAdapter for enums that allows having a fallback enum value when a deserialized string does not match any enum value. To use, add this as an adapter for your enum type on your Moshi.Builder:


Moshi moshi = new Moshi.Builder()
    .add(CurrencyCode.class, EnumJsonAdapter.create(CurrencyCode.class)
        .withUnknownFallback(CurrencyCode.USD))
    .build();
