## Class ConvertListeners

- java.lang.Object
- - org.apache.jmeter.engine.ConvertListeners

- All Implemented Interfaces:
    HashTreeTraverser

      public class ConvertListeners
      extends Object
      implements HashTreeTraverser

  Converts the Remoteable Test and Sample Listeners in the test tree by wrapping them with RemoteSampleListeners so that the samples are returned to the client. N.B. Does not handle ThreadListeners.

    Constructor and Description
    `ConvertListeners()`

  - ### Method Summary

    All Methods Instance Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `void` | `addNode(Object node, HashTree subTree)` The tree traverses itself depth-first, calling addNode for each object it encounters as it goes.
    `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.

    - #### 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`
