extract

public static Path extract(Path path,
 IndexRangeNegative range)
                    throws DerivePathException

Extracts a sub-path from a Path by only retaining a range of elements.

The name-elements are a split of the Path by the directory-separator. See the Path Javadoc.

All indices begin at 0 (for the first element), and can also accept negative-indices which count backwards from the end.

e.g. -1 is the last element; -2 is the second-last element.

Parameters:

path - the path to find a sub-path for.

range - which elements to include or not.

Returns:

a newly created Path containing only the elements of path in the sub-range.

Throws:

DerivePathException - if the range contains invalid indices.
