public abstract class DefaultListJsonReader<EntityType>
extends EntityJsonReader<List<EntityType>>

Base class to convert json as List.

It follow the classic Nuxeo list format :

 {
   "entity-type": "GIVEN_ENTITY_TYPE",
   "entries": [
     {...}, <-- A Reader must be able to manage this format.
     {...},
     ...
     {...}
   ]
 }
 

This reader delegates the unmarshalling of entries to the MarshallerRegistry. A Json Reader compatible with the required type and the json format must be registered.
