Class AvroJacksonDeserializers

java.lang.Object

com.fasterxml.jackson.databind.module.SimpleDeserializers

com.cerner.beadledom.avro.AvroJacksonDeserializers

All Implemented Interfaces:

com.fasterxml.jackson.databind.deser.Deserializers, Serializable

public class AvroJacksonDeserializers
extends com.fasterxml.jackson.databind.module.SimpleDeserializers

Jackson deserializers for Avro SpecificRecordBase types.

This class ensures that Jackson deserializes Avro class by using the generated builder classes rather than by directly instantiating the generated value classes. This ensures that any fields not specified in the input JSON will have their default values (if any) applied, rather than being left null. It only works if there is a static nested class named @{code Builder} inside the value class, with a build method; the default Avro generator templates produce these.
