No, for two reasons: 1. JsonNode is singly linked, only parent -> child linkage (not a problem for root node itself, but in general) 2. JsonNode does not have JsonLocation, since this is not needed in general
to get location information, you need to use JsonParser directly, or sub-class JsonNode implementation and JsonNodeFactory. Latter might be doable as you can add property to hold location information But you'd need to build the tree yourself from JsonParser: this is not very complicated (JsonNodeDeserializer shows how to do it, although it's more complicated than what you'd need). -+ Tatu +- On Sat, Nov 12, 2016 at 9:13 AM, <list+com.fasterxml.jackson-u...@io7m.com> wrote: > Hello. > > Let's assume I've received an ObjectNode representing the root of a > parsed JSON document.
