This is exactly what I needed.

Please, make sure you got the latest update, because you quoted not the most recent one published on this thread.

Please fix it.

Please fix it.

Thank you. I fixed it a bit differently.

struct TestCacheInputExtended: public TestCacheInput
{
   ...   
   void operator=(const TestCacheInput &other)
   {
      TestCacheInput::operator=(other);
      extend();
   }
};

It's more convenient and logical, because extend() doesn't need to be explicitly called.

NB: the attached file contains other useful edits.

Thanks, now it's even more practical.
