             Summary: Improving Converters
                 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?
