java - Jackson custom deserializer for one field with polymorphic types - Stack Overflow

I tried to debug in jackson source code and find out that in the method

deserialize(JsonParser jp, DeserializationContext ctxt) of

SettableBeanProperty.java

when the _valueTypeDeserializer isn't null, it will never use _valueDeserializer.

Is this a correct assumption that TypeDeserializer should be more proper than ValueDeserializer?
