- ## Method Summary

  Modifier and Type
  Method
  Description
  `void`
  `addNode(Object node, HashTree subTree)`
  The tree traverses itself depth-first, calling addNode for each object it encounters as it goes.
  `void`
  `processPath()`
  Process path is called when a leaf is reached.
  `void`
  `subtractNode()`
  Indicates traversal has moved up a step, and the visitor should remove the top node from its stack structure.

- ## Method Details

  - ### addNode

    public void addNode(Object node, HashTree subTree)
    The tree traverses itself depth-first, calling addNode for each object it encounters as it goes. This is a callback method, and should not be called except by a HashTree during traversal.
    Specified by:
      `addNode` in interface `HashTreeTraverser`
    Parameters:
      `node` - the node currently encountered
      `subTree` - the HashTree under the node encountered

  - ### subtractNode

    public void subtractNode()
    Indicates traversal has moved up a step, and the visitor should remove the top node from its stack structure. This is a callback method, and should not be called except by a HashTree during traversal.
    Specified by:
      `subtractNode` in interface `HashTreeTraverser`

  - ### processPath

    public void processPath()
    Process path is called when a leaf is reached. If a visitor wishes to generate Lists of path elements to each leaf, it should keep a Stack data structure of nodes passed to it with addNode, and removing top items for every `HashTreeTraverser.subtractNode()` call. This is a callback method, and should not be called except by a HashTree during traversal.
    Specified by:
      `processPath` in interface `HashTreeTraverser`
