c++ template casting

Question

I\'m a little lost in how to cast templates. I have a function foo which takes a parameter of type ParamVector*. I would like to pass in a P

I'm not sure but maybe you need some like this:

template< typename TypeT >
struct ParamVector
{
    template < typename NewTypeT >
    operator ParamVector< NewTypeT >()
    {
        ParamVector< NewTypeT > result;
        // do some converion things
        return result;
    }

    template< typename NewTypeT >
    ParamVector( const ParamVector< NewTypeT > &rhs )
    {
        // convert
    }

    template < typename NewTypeT >
    ParamVector& operator=( const ParamVector< NewTypeT > &rhs )
    {
        // do some conversion thigns
        return *this;
    }


};
ParamVector< double > d1;
ParamVector< float > f1;
f1 = d1;

You can choose use conversion operator or operator= - I've provided both in my example.
