Re: [Tntnet-general] plain json through json deserializer

Hi,

the cxxtools::SerializationInfo is meant to be a generic data structure,which do not depend on the format. Using the serialization operator youcan convert C++ objects into a cxxtools::SerializationInfo. Json is justone format you can create from that.

Putting a raw type make the SerializationInfo depend on the format. Youare not able to create xml from that any more. It would really break theidea of the serialization framework.


I would prefer not to support hat.

Note that you can convert you existing json parts into aSerializationInfo using the json deserializer. Then you can use that tobuild the complete structure and serialize it into json again. It is notreally the fastest was but I guess it is a strange requirement also.

Hi,

I am in the process of extending the json serializer to accept arguments
which are json already and don't require further processing (my data
contains mixed elements - partly raw data requiring conversion as well as
json i'd like to output). As it so happens I have developed a patch which
does not work as expected (see below). Any idea what I am missing ?

I found the problem! Below you will find a revised version of my original
patch. Please let me know if you consider the patch for inclusion. I'd be
happy to help to make that happen.

Thanks,
Marek
