public class ExternalTypeHandler extends Object
Helper class that is used to flatten JSON structure when using "external type id" (seeJsonTypeInfo.As.EXTERNAL_PROPERTY
). This is needed to store temporary state and buffer tokens, as the structure is rearranged a bit so that actual type deserializer can resolve type and finalize deserialization.- Since:
