Class 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.

      • 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 of Controller
