Question

I have really heavy task to achieve and I haven’t found any solution good enough. So, here is the description:
– task is to evaluate multiple single dimension arrays which number can vary
– good news is that it is possible to specify types of arrays

And desirable way of doing it:
– creating a class with constructor that accepts variable number of arrays
– these arrays should be also used as properties (private members), so multiple operations can be done on(with) them during lifecycle of object

How I tried to do it:
– constructor member function with variable number of paramaters (I’m not sure why this doesn’t work)
– constructor with vector should be better way, but how to store arrays that type is specified in separate array, meaning you can’t expect certain datatype for certain array in advance
– I tried to declare variable number of arrays as private members with preprocessor, but it seems loops and other code do not work well inside private: declaration

Any idea from anybody?

Answer 1

constructor that accepts variable number of arrays:

vector< vector<T> > ?

the inner vectors can be of different sizes but must be of the same type.

constructor member function with variable number of parameters

You can use a function with variable number of parameters that creates a class, look at how boost::bind works, that takes lots of different parameter lists.

boost mpl may answer what you are trying to do, although it is rather unclear.
