Method Detail

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 interfaceHashTreeTraverser
- Parameters:
node
- the node currently encounteredsubTree
- 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 interfaceHashTreeTraverser
-
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 everyHashTreeTraverser.subtractNode()
call. This is a callback method, and should not be called except by a HashTree during traversal.- Specified by:
processPath
in interfaceHashTreeTraverser

getControllersToRoot
public List<Controller> getControllersToRoot()
Returns all controllers that where in Tree down to nodeToFind in reverse order (from leaf to root)- Returns:
- List of
Controller
