trait Path extends AnyRef

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"

Abstract Value Members

  1. abstract def isAbsolute: Boolean

    Returns true if the path is absolute.

  2. abstract 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 "/".

  3. abstract 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

  4. abstract def parent: Path

    Returns the parent path.

    Returns the parent path.

    returns

    the parent of path

    Exceptions thrown

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

  5. abstract 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 "/"

  6. abstract 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

  7. abstract def path: String

    Returns the path.

    Returns the path.

    returns

    the path

  8. abstract def resolve(path: Path): Path

    Resolves the given path relative to this path.

    Resolves the given path relative to this path.

    path

    the path to resolve against this path

    returns

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

  9. abstract 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
    path

    the path to resolve against this path

    returns

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