    - #### JMeterTreeModel

          public JMeterTreeModel()

    - #### JMeterTreeModel

          @Deprecated
          public JMeterTreeModel(Object o)

      Deprecated. - only for use by JMeter class!
      Hack to allow TreeModel to be used in non-GUI and headless mode.
      Parameters:
        `o` - - dummy

  - ### Method Detail

    - #### getNodesOfType

          public List<JMeterTreeNode> getNodesOfType(Class<?> type)

      Returns a list of tree nodes that hold objects of the given class type. If none are found, an empty list is returned.
      Parameters:
        `type` - The type of nodes, which are to be collected
      Returns:
        a list of tree nodes of the given `type`, or an empty list

    - #### getNodeOf

          public JMeterTreeNode getNodeOf(TestElement userObject)

      Get the node for a given TestElement object.
      Parameters:
        `userObject` - The object to be found in this tree
      Returns:
        the node corresponding to the `userObject`

    - #### addSubTree

          public HashTree addSubTree(HashTree subTree,
                                     JMeterTreeNode current)
                              throws IllegalUserActionException

      Adds the sub tree at the given node. Returns a boolean indicating whether the added sub tree was a full test plan.
      Parameters:
        `subTree` - The `HashTree` which is to be inserted into `current`
        `current` - The node in which the `subTree` is to be inserted. Will be overridden, when an instance of `TestPlan`
      Returns:
        newly created sub tree now found at `current`
      Throws:
        `IllegalUserActionException` - when `current` is not an instance of `AbstractConfigGui` and no instance of `TestPlan` `subTree`

    - #### addComponent

          public JMeterTreeNode addComponent(TestElement component,
                                             JMeterTreeNode node)
                                      throws IllegalUserActionException

      Add a `TestElement` to a `JMeterTreeNode`
      Parameters:
        `component` - The `TestElement` to be used as data for the newly created node
        `node` - The `JMeterTreeNode` into which the newly created node is to be inserted
      Returns:
        new `JMeterTreeNode` for the given `component`
      Throws:
        `IllegalUserActionException` - when the user object for the `node` is not an instance of `AbstractConfigGui`

    - #### removeNodeFromParent

          public void removeNodeFromParent(JMeterTreeNode node)

    - #### getCurrentSubTree

          public HashTree getCurrentSubTree(JMeterTreeNode node)

      Get the current sub tree for a `JMeterTreeNode`
      Parameters:
        `node` - The `JMeterTreeNode` from which the sub tree is to be taken
      Returns:
        newly copied sub tree

    - #### getTestPlan

          public HashTree getTestPlan()

      Get the `TestPlan` from the root of this tree
      Returns:
        The `TestPlan` found at the root of this tree

    - #### clearTestPlan

          public void clearTestPlan()

      Clear the test plan, and use default node for test plan. N.B. Should only be called by `GuiPackage.clearTestPlan()`

    - #### clearTestPlan

          public void clearTestPlan(TestElement testPlan)

      Clear the test plan, and use specified node for test plan N.B. Should only be called by `GuiPackage.clearTestPlan(TestElement)`
      Parameters:
        `testPlan` - the node to use as the testplan top node
