Path

trait Path

Represents an ''absolute'' or ''relative'' path to a node in ZooKeeper.

An ''absolute'' path starts with the / character. All other forms are considered ''relative''. Paths are virtually identical to those on Unix file systems and may include both . and .. parts, indicating the current and parent node, respectively.

Examples:

"/"
"../foo"
"/foo/bar"
"./foo/../bar"
Companion:
object
class Object
trait Matchable
class Any

Value members

Abstract methods

def isAbsolute: Boolean

Returns true if the path is absolute.

Returns true if the path is absolute.

def name: String

Returns the name of the last part of the path.

Returns the name of the last part of the path.

Examples:

"" parent is ""
"/" parent is ""
"/foo" parent is "/"
"/foo/bar" parent is "/foo"
"foo/bar" parent is "foo"
Returns:

the last part of path, which is an empty string if path is either "" or "/".

def normalize: Path

Returns the normalized form of this path.

Returns the normalized form of this path.

The normalization process entails the removal of . and .. parts where possible.

Examples:

"/.." normalizes to "/"
"/foo/.." normalizes to "/"
"/foo/../bar" normalizes to "/bar"
"./foo" normalizes to "foo"
"foo/." normalizes to "foo"
"foo/.." normalizes to ""
"foo/./bar" normalizes to "foo/bar"
"foo/../bar" normalizes to "bar"
Returns:

the normalized form of this path

def parent: Path

Returns the parent path.

Returns the parent path.

Returns:

the parent of path

Throws:
NoSuchElementException

if removal of name from path yields "" or "/"

def parentOption: Option[Path]

Returns the parent path wrapped in an Option.

Returns the parent path wrapped in an Option.

Returns:

a Some containing the parent of path or None if removal of name from path yields "" or "/"

def parts: Seq[String]

Returns a sequence containing the parts of the path.

Returns a sequence containing the parts of the path.

Parts represent the node names sandwiched between / characters. An ''absolute'' path, which is prefixed with /, always yields a sequence containing an empty string as the first element. The path "" contains no parts, hence an empty sequence is returned. In all other cases, parts are non-empty strings.

Examples:

"" parts ()
"/" parts ("/")
"/foo/bar" parts ("", "foo", "bar")
"foo/bar" parts ("foo", "bar")
Returns:

a sequence containing the parts of path

def path: String

Returns the path.

Returns the path.

Returns:

the path

def resolve(path: String): Path

Resolves the given path relative to this path.

Resolves the given path relative to this path.

Path resolution works as follows:

  • if path is empty, return this path
  • if path starts with /, return path
  • if this path is empty, return path
  • otherwise, return this path + / + path
Value parameters:
path

the path to resolve against this path

Returns:

a new path in which the given path is resolved relative to this path

def resolve(path: Path): Path

Resolves the given path relative to this path.

Resolves the given path relative to this path.

Value parameters:
path

the path to resolve against this path

Returns:

a new path in which the givne path is resolved relative to this path
