from

public static StringPath from(TagPath path)

parse

extend

public static StringPath extend(StringPath parent,
                                StringPath other)

makeRelative

public static StringPath makeRelative(StringPath toRelative,
                                      StringPath root)

isRelative

public static boolean isRelative(StringPath path)

removeRelative

public static StringPath removeRelative(StringPath relative,
                                        StringPath root)
