com.fasterxml.jackson.datatype.hibernate5.PersistentCollectionSerializer

All Implemented Interfaces:

com.fasterxml.jackson.databind.jsonFormatVisitors.JsonFormatVisitable, com.fasterxml.jackson.databind.jsonschema.SchemaAware, com.fasterxml.jackson.databind.ser.ContextualSerializer, com.fasterxml.jackson.databind.ser.ResolvableSerializer, Serializable

public class PersistentCollectionSerializer
extends com.fasterxml.jackson.databind.ser.ContainerSerializer<Object>
implements com.fasterxml.jackson.databind.ser.ContextualSerializer, com.fasterxml.jackson.databind.ser.ResolvableSerializer

Wrapper serializer used to handle aspects of lazy loading that can be used for Hibernate collection datatypes; which includes both Collection and Map types (unlike in JDK).
