Class HibernateProxySerializer

java.lang.Object

com.fasterxml.jackson.databind.JsonSerializer<org.hibernate.proxy.HibernateProxy>

com.fasterxml.jackson.datatype.hibernate4.HibernateProxySerializer

All Implemented Interfaces:

com.fasterxml.jackson.databind.jsonFormatVisitors.JsonFormatVisitable

public class HibernateProxySerializer
extends com.fasterxml.jackson.databind.JsonSerializer<org.hibernate.proxy.HibernateProxy>

Serializer to use for values proxied using HibernateProxy.

TODO: should try to make this work more like Jackson BeanPropertyWriter, possibly sub-classing it -- it handles much of functionality we need, and has access to more information than value serializers (like this one) have.
