Field Detail

### EMPTY_RELATIVE

    public static final Path EMPTY_RELATIVE

### SELF_PATH

    public static final Path SELF_PATH

### PARENT_PATH

    public static final Path PARENT_PATH

Constructor Detail

### BasicPath

    public BasicPath(List<Path.Segment> segments,
                     boolean absolute)

Parameters:
  `segments` - the segments
  `absolute` - true if this path is absolute, or false otherwise

Method Detail

### getAncestor

    public Path getAncestor(int degree)

  Return the path to the ancestor of the supplied degree. An ancestor of degree `x` is the path that is `x` levels up along the path. For example, `degree = 0` returns this path, while `degree = 1` returns the parent of this path, `degree = 2` returns the grandparent of this path, and so on. Note that the result may be unexpected if this path is not `normalized`, as a non-normalized path contains ".." and "." segments.

  Returns:
    the ancestor of the supplied degree

### getSegmentsOfParent

    protected Iterator<Path.Segment> getSegmentsOfParent()

  Method used by `AbstractPath.equals(Object)` implementation to quickly get an Iterator over the segments in the parent.

  Specified by:
    `getSegmentsOfParent` in class `AbstractPath`
  Returns:
    the iterator over the segments; never null, but may not have any elements
  See Also:
    `AbstractPath.getSegmentsOfParent()`

### getSegmentsList

    public List<Path.Segment> getSegmentsList()

  Get an unmodifiable list of the path segments.

  Returns:
    the unmodifiable list of path segments; never null

### isAbsolute

    public boolean isAbsolute()

  Return whether this path is an absolute path. A path is either relative or `absolute`. An absolute path starts with a "/".

  Returns:
    true if the path is absolute, or false otherwise

### isNormalized

    public boolean isNormalized()

  Return whether this path is normalized and contains no unnecessary "." segments and as few ".." segments as possible. For example, the path "../a" is normalized, while "/a/b/c/../d" is not normalized.

  Returns:
    true if this path is normalized, or false otherwise

### isRoot

    public boolean isRoot()

  Return whether this path represents the root path.

  Returns:
    true if this path is the root path, or false otherwise

### size

    public int size()

  Return the number of segments in this path.

  Returns:
    the number of path segments
