Class OAJacksonDeserializerLoader

java.lang.Object

com.viaoa.json.jackson.OAJacksonDeserializerLoader

public class OAJacksonDeserializerLoader
extends Object

Used by OAJson to convert JSON to OAObject(s).
This will find the existing OAObjects and Hubs and add/update/delete.

This supports object graphs, json from POJOs that might not have matching pkey properties.
For POJOs without direct pkey & fkey properties, it uses the following to find and update matching OAObjects

• Match using unique pkey property(s)
• Guid match
• ImportMatch properties
• Links that have a unique property match.
• Links that have an equals property path with a unique property match.
