PostOrder traversal of a binary tree.

What's the algorithm for a PostOrder traversal of a binary tree? This doesn't seem to be working.

public class POIterator implements Iterator{ private final Deque<BNode> someStack; BNode position; public POIterator(BNoderoot){ someStack = new LinkedList<BNode>(); someStack.push(root); }

public boolean hasNext(){return !someStack.isEmpty();}

public T next(){ position = someStack.pop(); if(position.hasLeftChild()){ someStack.push(position.getLeftNode()); next();} if(position.hasRightNode()){ someStack.push(position.getRightNode()); next();} return position.getData(); } }

Is there something missing from my code. An error/bug perhaps?
