public  void addTestElement(TestElement child)

 public boolean canRemove()
Called by Remove to determine if it is safe to remove the element. The
element can either clean itself up, and return true, or the element can
return false.

 public  void clear()
Clear the TestElement of all data.

 public Object clone()

 public JMeterProperty getProperty(String propName)
Given the name of the property, returns the appropriate property from
JMeter. If it is null, a NullProperty object will be returned.

 public boolean getPropertyAsBoolean(String key)
Return a property as a boolean value.

 public float getPropertyAsFloat(String key)

 public int getPropertyAsInt(String key)

 public long getPropertyAsLong(String key)

 public String getPropertyAsString(String key)

 public JMeterContext getThreadContext()

 public String getThreadName()

 public boolean isEnabled()
Check if ENABLED property is present and true ; defaults to true

 public boolean isRunningVersion()
Returns true or false whether the element is the running version.

 public boolean isTemporary(JMeterProperty property)
Test whether a given property is only a temporary resident of the
TestElement

 public PropertyIterator propertyIterator()
Get a Property Iterator for the TestElements properties.

 public  void recoverRunningVersion()
Tells the test element to return to the state it was in when
makeRunningVersion() was called.

 public  void removeProperty(String key)

 public  void setProperty(JMeterProperty property)
Sets and overwrites a property in the TestElement. This call will be
ignored if the TestElement is currently a "running version".

 public  void setProperty(String key,
    String value)

 public  void setRunningVersion(boolean run)
Make the test element the running version, or make it no longer the
running version. This tells the test element that it's current state must
be retrievable by a call to recoverRunningVersion(). It is kind of like
making the TestElement Read- Only, but not as strict. Changes can be made
and the element can be modified, but the state of the element at the time
of the call to setRunningVersion() must be recoverable.

 public  void setTemporary(JMeterProperty property)
Indicate that the given property should be only a temporary property in
the TestElement

 public  void setThreadContext(JMeterContext threadContext)

 public  void setThreadName(String threadName)

 public  void threadFinished()
Called at the end of each thread. TODO - should it hava a parameter?

 public  void threadStarted()
Called at the start of each thread. TODO - should it hava a parameter?

 public  void traverse(TestElementTraverser traverser)
Convenient way to traverse a test element.
