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)

Description copied from interface: Path

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()

Description copied from class: AbstractPath

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

getSegmentsList

public List<Path.Segment> getSegmentsList()

Description copied from interface: Path

Get an unmodifiable list of the path segments.

Returns:

the unmodifiable list of path segments; never null

isAbsolute

public boolean isAbsolute()

Description copied from interface: Path

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()

Description copied from interface: Path

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()

Description copied from interface: Path

Return whether this path represents the root path.

Returns:

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

size

public int size()

Description copied from interface: Path

Return the number of segments in this path.

Returns:

the number of path segments
