Yes, for delegation you would retrieve a JsonDeserializer via DeserializationContext.
However, for performance reasons this is most often done by implementing ContextualDeserializer, and handling lookups from method `createContextual()` which is called once after construction. This method can access annotations, fetch deserializers to delegate, and then construct a new instance with settings (it should NOT modify instance itself, as it may be shared among multiple properties). Method to call depends on situation; most likely it is one of: * findContextualValueDeserializer(): handles contextualization (as name implies), requires `BeanProperty` (which is passed to `createContextual()` * findRootValueDeserializer(): called when this is the initial root deserializer; also wraps TypeDeserializer for polymorphic types -+ Tatu +- On Thu, Jul 14, 2016 at 8:39 AM, <[email protected]> wrote: > So I'm writing a custom deserializer, extending StdDeserializer<T>. > > I want the JSON structure to be slightly different to "normal", hence > needing my own serializer and deserializer. > > Within the serializer I just call writeObjectField when I want to > serialize the properties of my object, but I can't work out what the > reverse of that is. > > So within my deserializer I want to be able to deserialize a value of > given Class.
