java.lang.Object com.fasterxml.jackson.databind.jsontype.TypeSerializer com.fasterxml.jackson.databind.jsontype.impl.TypeSerializerBase com.fasterxml.jackson.databind.jsontype.impl.AsExternalTypeSerializer
public class AsExternalTypeSerializer
Type serializer that preferably embeds type information as an "external"
type property; embedded in enclosing JSON object.
Note that this serializer should only be used when value is being output
at JSON Object context; otherwise it can not work reliably, and will have
to revert operation similar to AsPropertyTypeSerializer
.
Note that implementation of serialization is bit cumbersome as we must serialized external type id AFTER object; this because callback only occurs after field name has been written.
