Class PathParentIterator

  • All Implemented Interfaces:
    java.util.Iterator<java.lang.String>

    public class PathParentIterator
    extends java.lang.Object
    implements java.util.Iterator<java.lang.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.

      Modifier and Type Method Description
      java.lang.Iterable<java.lang.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​(java.lang.String path)
      Return a new PathParentIterator that iterates from the given path to all parents.
      static PathParentIterator forPathOnly​(java.lang.String path)
      Return a new PathParentIterator that only returns the given path - i.e.
      boolean hasNext()  
      java.lang.String next()  
      void remove()
