## org.apache.jmeter.engine
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 Summary
`ConvertListeners()`

Method Summary
`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.

Methods inherited from class java.lang.Object

Constructor Detail

### ConvertListeners

    public ConvertListeners()

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`
