Romain Manni-Bucau commented on JOHNZON-72:
-------------------------------------------

Annotation can just use  Class, if ambiguous just fail - no chain please to 
ensure understanding is simple and not needed since controllable by model or 
builder.

For the name: JsonConverter? Not sure it is better bit what i can think of now.

>                 Key: JOHNZON-72
>                 URL: https://issues.apache.org/jira/browse/JOHNZON-72
>             Project: Johnzon
>          Issue Type: New Feature
>    Affects Versions: 0.9.3-incubating
>            Reporter: Mark Struberg
>
> Converter, Adapter and ObjectConverter are kind of fitting into the same 
> ballpark.
> * Converter: convert from/to a single JSON attribute String 
> * Adapter: converts from/to different classes during object de/serialisation
> * ObjectConverter: similar to Adapter, but allows for having much more 
> control over the conversion.
> 1.) I'd like to introduce a common marker interface for them. 
>  * That could be used for registering a @JohnzonConverter which could be any 
> of the 3
>  * That could  be used for MapperBuilder#addAdapter() methods 
> 2.) ObjectConverter is not a good enough name imo. If you have a better idea, 
> then please shout out ;)
> 3.) We might think about using @Priority on Adapters to allow a fallback 
> chain handling?
