Detailed Description

template<typename String, typename Delims>
class fz::strtokenizer< String, Delims >

Container-like class that can be used to iterate over tokens in a string.

The class will keep a copy of any temporary constructor's parameter. strtokenizer must live longer than the iterators created from it.

Access through the iterators returns views, make sure non-temporary arguments to strtokenizer constructur live longer than the iterators.

Do not modify a string for which there is an strtokenizer instance.

Always use the construction guide for this class, never explictly use the template parameters.

Usage example:

for (auto t : fz::strtokenizer("foo,baz,,bar", ",", true)) {
  std::cout << t << "\n";
}
 
// Will print the following:
//     foo
//     baz
//     bar
