TypeSerializer.writeTypePrefix(JsonGenerator, WritableTypeId)
and matching value write have been called, passing WritableTypeId
returned.
Usual idiom is:
// Indicator generator that type identifier may be needed; generator may write // one as suggested, modify information, or take some other action // NOTE! For Object/Array types, this will ALSO write start marker! WritableTypeId typeIdDef = typeSer.writeTypePrefix(gen, typeSer.typeId(value, JsonToken.START_OBJECT)); // serializing actual value for which TypeId may have been written... like // NOTE: do NOT write START_OBJECT before OR END_OBJECT after: g.writeStringField("message", "Hello, world!" // matching type suffix call to let generator chance to add suffix, if any // NOTE! For Object/Array types, this will ALSO write end marker! typeSer.writeTypeSuffix(gen, typeIdDef);
