...int uses the @NotNull constraint above, and @Size whose definition differs based on the object but should be self explanitory.

What's the best way to iterate over two or more containers simultaneously
...over indices. But not with the classical for loop but instead with a range-based for loop over the indices:
for(unsigned i : indices(containerA)) {
