PathParentIterator (Apache ZooKeeper - Server 3.9.1 API)

java.lang.Object
- org.apache.zookeeper.server.watch.PathParentIterator

All Implemented Interfaces:

Iterator<String>
```
public class PathParentIterator
extends Object
implements Iterator<String>
```
Iterates over a ZooKeeper path. Each iteration goes up one parent path. Thus, the effect of the iterator is to iterate over the initial path and then all of its parents.

Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`Iterable<String>`	`asIterable()`	Return an Iterable view so that this Iterator can be used in for each statements.
`boolean`	`atParentPath()`	Returns true if this iterator is currently at a parent path as opposed to the initial path given to the constructor
`static PathParentIterator`	`forAll(String path)`	Return a new PathParentIterator that iterates from the given path to all parents.
`static PathParentIterator`	`forPathOnly(String path)`	Return a new PathParentIterator that only returns the given path - i.e.
`boolean`	`hasNext()`
`String`	`next()`
`void`	`remove()`

- Method Detail
  - forAll
```
public static PathParentIterator forAll(String path)
```
    Return a new PathParentIterator that iterates from the given path to all parents.
    
    Parameters:
    
    path - initial path
  - forPathOnly
```
public static PathParentIterator forPathOnly(String path)
```
    Return a new PathParentIterator that only returns the given path - i.e. does not iterate to parent paths.
    
    Parameters:
    
    path - initial path
  - asIterable
```
public Iterable<String> asIterable()
```
    Return an Iterable view so that this Iterator can be used in for each statements. IMPORTANT: the returned Iterable is single use only
    
    Returns:

  - atParentPath
```
public boolean atParentPath()
```
    Returns true if this iterator is currently at a parent path as opposed to the initial path given to the constructor
    
    Returns:
    
    true/false
  - next
```
public String next()
```
    Specified by:
    
    next in interface Iterator<String>
