Class LegacyJsonFormat

java.lang.Object

org.datavec.api.transform.serde.legacy.LegacyJsonFormat

public class LegacyJsonFormat
extends Object

This class defines a set of Jackson Mixins - which are a way of using a proxy class with annotations to override the existing annotations. In 1.0.0-beta, we switched how subtypes were handled in JSON ser/de: from "wrapper object" to "@class field". We use these mixins to allow us to still load the old format
