public  void clearGui()
Clear the gui and return it to initial default values. This is necessary
because most gui classes are instantiated just once and re-used for
multiple test element objects and thus they need to be cleared between
use.

 public  void configure(TestElement element)
The GUI must be able to extract the data from the TestElement and update
all GUI fields to represent those data. This method is called to allow
JMeter to show the user the GUI that represents the test element's data.

 public JPopupMenu createPopupMenu()
When a user right-clicks on the component in the test tree, or selects
the edit menu when the component is selected, the component will be asked
to return a JPopupMenu that provides all the options available to the
user from this component.

 public TestElement createTestElement()
JMeter test components are separated into a model and a GUI
representation. The model holds the data and the GUI displays it. The GUI
class is responsible for knowing how to create and initialize with data
the model class that it knows how to display, and this method is called
when new test elements are created.

 public String getDocAnchor()
Get the component's document anchor name. Used by Help to find the
appropriate location in the documentation

 public String getLabelResource()
Get the component's resource name, which getStaticLabel uses to derive
the component's label in the local language. The resource name is fixed,
and does not vary with the selected language.

Normally this method should be overriden in preference to overriding
getStaticLabel(). However where the resource name is not available or required,
getStaticLabel() may be overridden instead.

 public Collection getMenuCategories()
This is the list of add menu categories this gui component will be
available under. For instance, if this represents a Controller, then the
MenuFactory.CONTROLLERS category should be in the returned collection.
When a user right-clicks on a tree element and looks through the "add"
menu, which category your GUI component shows up in is determined by
which categories are returned by this method. Most GUI's belong to only
one category, but it is possible for a component to exist in multiple
categories.

 public String getName()
Gets the name of the JMeter GUI component. The name of the component is
used in the Test Tree as the name of the tree node.

 public String getStaticLabel()
Get the component's label. This label is used in drop down lists that
give the user the option of choosing one type of component in a list of
many. It should therefore be a descriptive name for the end user to see.
It must be unique to the class.

It is also used by Help to find the appropriate location in the
documentation.

Normally getLabelResource() should be overridden instead of
this method; the definition of this method in AbstractJMeterGuiComponent
is intended for general use.

 public boolean isEnabled()
Test GUI elements can be disabled, in which case they do not become part
of the test when run.

 public  void modifyTestElement(TestElement element)
GUI components are responsible for populating TestElements they create
with the data currently held in the GUI components. This method should
overwrite whatever data is currently in the TestElement as it is called
after a user has filled out the form elements in the gui with new
information.

 public  void setEnabled(boolean enabled)
Set whether this component is enabled.

 public  void setName(String name)
Sets the name of the JMeter GUI Component. The name of the component is
used in the Test Tree as the name of the tree node.

 public  void setNode(TreeNode node)
Sets the tree node which this component is associated with.
