Detailed Description

Path iterator.

This is an input iterator that iterates over the individual components in path. The traversal order is as follows:

• The root-name element, if present.
• The root-directory element, if present.
• Each successive filename element, if present.
• Dot, if one or more trailing non-root slash characters are present. Traversing backwards is possible with reverse_iterator

Iteration examples. Each component is separated by ',':

/          => /
/foo       => /,foo
foo/       => foo,.
/foo/bar   => /,foo,bar
../        => ..,.
C:\foo\bar => C:,\,foo,bar
