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

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 ?

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
