Assignment of read only location, class with const method trying to write to private member variable [modified]

[jeweladdict]

I'm stumped on this one I have a class, with a private unsigned char array. I have a class method which is const. It is trying to write to the private unsigned char array, but I get the assignment of read only location. I can't touch the headers/remove the const because it is an inherited virtual function. How do I access the unsigned char array?

I presume it's private in your derived class (it's difficult to tell, as you haven't posted the code...). In that case, declare it as mutable. That way you can modify it even in a const method. However, unless (say) the array is a cache, is the design correct?

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p
