Method Detail

addNode

public void addNode(java.lang.Object key,
                    HashTree subTree)

Description copied from interface: HashTreeTraverser

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

---

subtractNode

public void subtractNode()

Description copied from interface: HashTreeTraverser

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()

Description copied from interface: HashTreeTraverser

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() 55 call. This is a callback method, and should not be called except by a HashTree during traversal.

Specified by:

processPath in interface HashTreeTraverser

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

getSpaces

private java.lang.String getSpaces()
