Re: [Boost-users] How to Boost serialize a Eigen::Matrix class

Hi, i directly linked to the example code in question where the "non-intrusive" version was explained. You have to create a function namespace boost::seialization with the following signature namespace boost { namespace serialization { template void serialize(Archive & ar, Eigen::Matrix & g, const unsigned int version) { //Serialization code here } } } with the Eigen matrix type i am not sure since i don't use this library. And i also don't know how the serialization code itself should lool like - that's your work. Greetings, Oswin On 2012-09-27 11:53, Dip Ghosh wrote:

Hi Oswin, Thanks for your reply. I have seen the tutorial already. I am new to boost so I apologize in advance if my question is very basic. So shall I have to put the serialize part inside my Eigen::Matrix class to work ? or can I put it inside my class ? Can you give me a small example please or explain a bit ?

Regards, Dip

Hi, I have used Eigen::Matrix class in my project. Now i wants to serialize the value of it through Boost::Serialize. Can someone help me on how to achieve that.

My class is following,

class RandomNode { private: friend class boost::serialization::access; template<class Archive> void serialize(Archive & ar, const unsigned int version) { ar & is_leaf_; ar & depth_; ar & num_classes_; ar & num_features_; // Split node members ar & random_feature_indices_; ar & random_feature_weights_; ar & threshold_; ar & leftChild_; ar & rightChild_;

} bool is_leaf_; int depth_; int num_classes_; int num_features_;

// Split node members VectorXi random_feature_indices_; VectorXd random_feature_weights_; double threshold_; RandomNode* leftChild_; RandomNode* rightChild_; // Methods and so on }

And i am getting the following error :

/usr/include/boost/serialization/access.hpp:118:9: error: ‘class Eigen::Matrix’ has no member named ‘serialize’

thanks in advance.

Regards, Dip
