Class MatsSocketStatics.MessageToStringDeserializer

java.lang.Object

com.fasterxml.jackson.databind.JsonDeserializer<java.lang.Object>

io.mats3.matssocket.impl.MatsSocketStatics.MessageToStringDeserializer

All Implemented Interfaces:

com.fasterxml.jackson.databind.deser.NullValueProvider

Enclosing interface:

MatsSocketStatics

public static class MatsSocketStatics.MessageToStringDeserializer
extends com.fasterxml.jackson.databind.JsonDeserializer<java.lang.Object>

A MatsSocketServer.MatsSocketEnvelopeWithMetaDto will be Deserialized (made into object) with the "msg" field directly to the JSON that is present there (i.e. a String, containing JSON), using this class. However, upon serialization, any object there will be serialized to a JSON String (UNLESS it is a MatsSocketStatics.DirectJson, in which case its value is copied in verbatim). The rationale is that upon reception, we do not (yet) know which type (DTO class) this message has, which will be resolved later - and then this JSON String will be deserialized into that specific DTO class.
