public void serializeWithType(Map<?,?> value, JsonGenerator jgen, SerializerProvider provider, TypeSerializer typeSer) throws IOException, JsonGenerationException
JsonSerializer
Default implementation will ignore serialization of type information,
and just calls JsonSerializer.serialize(T, org.codehaus.jackson.JsonGenerator, org.codehaus.jackson.map.SerializerProvider)
: serializers that can embed
type information should override this to implement actual handling.
Most common such handling is done by something like:
// note: method to call depends on whether this type is serialized as JSON scalar, object or Array! typeSer.writeTypePrefixForScalar(value, jgen); serialize(value, jgen, provider); typeSer.writeTypeSuffixForScalar(value, jgen);
