Re: [Boost-users] how to Serialize boost::Multiaray

12 Jun 2007


      I did take a look a year or so ago when the issue came up in a  
project, but we did not need it in the end. It seemed to me finally  
that an intrusive serialization is best, and you would need to modify  
boost/multiarray.hpp.

how should i do that, the thing is that i am working in a network

have to excuse my english i am from cuba.
i have this code but i don't know how to call it inside a class  
were i already have a serialize methods for other parameters of the  
class, i also want to make an xml output file.

I want to know how can i serialize with boost::serialization a two
dimensions boost::multiarray.
You will need to implement serialization support in boost::multiarray
