Re: [Boost-users] How to inherit from boost::multi_array

Hi Ron,

 

How do you "cast "other" to the multi_array type" here? I used 

 

      Array (const Array& other) : boost::multi_array<double,2>(
const_cast<const boost::multi_array<double,2>& > other)

      {

      }

 

And it failed to compile. 

 

Thank for your help,

 

Yan

Greetings Yan, 

 

I do not recall the context of the problem you describe below, but It
appears that the definition: 

 

Array (const Array& other) : 

boost::multi_array<double, 2> (other) 

{} 

 

is the problem. the above expression will call the templated
constructor. I believe that the solution here is to cast "other" to the
multi_array type. That should result in the proper constructor call. 

 

HTH,
