Class FindTestElementsUpToRootTraverser

java.lang.Object
  org.apache.jmeter.threads.FindTestElementsUpToRootTraverser

All Implemented Interfaces:

HashTreeTraverser

public class FindTestElementsUpToRootTraverser
extends Object
implements HashTreeTraverser

HashTreeTraverser implementation that stores in a Stack all the Test Elements on the path to a particular node.

Constructor Summary

FindTestElementsUpToRootTraverser(Object nodeToFind)

Method Summary

void	addNode(Object node, HashTree subTree) The tree traverses itself depth-first, calling addNode for each object it encounters as it goes.
List<Controller>	getControllersToRoot() Returns all controllers that where in Tree down to nodeToFind in reverse order (from leaf to root)
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.

Constructor Detail

FindTestElementsUpToRootTraverser

public FindTestElementsUpToRootTraverser(Object nodeToFind)

Parameters:

nodeToFind - Node to find

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 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

getControllersToRoot

public List<Controller> getControllersToRoot()

Returns all controllers that where in Tree down to nodeToFind in reverse order (from leaf to root)

Returns:

List
