abstract class JacksonJsonMigration extends AnyRef
Data migration of old formats to current format can
be implemented in a concrete subclass and configured to
be used by the JacksonJsonSerializer for a changed class.
It is used when deserializing data of older version than the #currentVersion. You implement the transformation of the JSON structure in the #transform method. If you have changed the class name you should override #transformClassName and return current class name.

Abstract Value Members
- abstract def currentVersion: Int
Define current version.
Define current version. The first version, when no migration was used, is always 1.
- abstract def transform(fromVersion: Int, json: JsonNode): JsonNode
Implement the transformation of the old JSON structure to the new JSON structure.
Implement the transformation of the old JSON structure to the new JSON structure. The
JsonNodeis mutable so you can add and remove fields, or change values. Note that you have to cast to specific sub-classes such asObjectNodeandArrayNodeto get access to mutators.- fromVersion
the version of the old data
- json
the old JSON data
