Annotation Type FallbackOnNull

@Documented
 @JsonQualifier
 @Retention(value=RUNTIME)
 @Target(value={FIELD,METHOD})
public @interface FallbackOnNull

Indicates that the annotated field may be null in the json source and thus requires a fallback value.

To leverage from FallbackOnNull ADAPTER_FACTORY must be added to your Moshi instance:

   Moshi moshi = new Moshi.Builder()
      .add(FallbackOnNull.ADAPTER_FACTORY)
      .build();
