[edit] Parameters
(none)
[edit] Return value
true if the path is empty, false otherwise.
[edit] Notes
An empty path can be obtained by calling clear and by default-constructing a path. It can also be returned by a path decomposition function (such as extension) if the corresponding component is not present in the path.
An empty path is classified as a relative path.
