    - #### LoopControlPanel

          public LoopControlPanel()

      Create a new LoopControlPanel as a standalone component.

    - #### LoopControlPanel

          public LoopControlPanel(boolean displayName)

      Create a new LoopControlPanel as either a standalone or an embedded component.
      Parameters:
        `displayName` - indicates whether or not this component should display its name. If true, this is a standalone component. If false, this component is intended to be used as a subpanel for another component.

  - ### Method Detail

    - #### getLoopsLabel

          @API(status=EXPERIMENTAL)
          public JLabel getLoopsLabel()

    - #### getInfinite

          @API(status=EXPERIMENTAL)
          public JCheckBox getInfinite()

    - #### getLoops

          @API(status=EXPERIMENTAL)
          public JTextField getLoops()

    - #### configure

          public void configure(TestElement element)

      A newly created component can be initialized with the contents of a Test Element object by calling this method. The component is responsible for querying the Test Element object for the relevant information to display in its GUI.
      Specified by:
        `configure` in interface `JMeterGUIComponent`
      Overrides:
        `configure` in class `AbstractJMeterGuiComponent`
      Parameters:
        `element` - the TestElement to configure

    - #### createTestElement

          public TestElement createTestElement()

      Description copied from interface: `JMeterGUIComponent`
      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.

      The canonical implementation looks like this:

           public TestElement createTestElement() {
               TestElementXYZ el = new TestElementXYZ();
               modifyTestElement(el);
               return el;
           }

      Specified by:
        `createTestElement` in interface `JMeterGUIComponent`
      Returns:
        the Test Element object that the GUI component represents.

    - #### modifyTestElement

          public void modifyTestElement(TestElement lc)

      Description copied from interface: `JMeterGUIComponent`
      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.

      The canonical implementation looks like this:

           public void modifyTestElement(TestElement element) {
               element.clear(); // many implementations use this
               configureTestElement(element);
               // Using the element setters (preferred):
               TestElementXYZ xyz = (TestElementXYZ) element;
               xyz.setState(guiState.getText());
               xyz.setCode(guiCode.getText());
               ... other GUI fields ...
               // or directly (do not use unless there is no setter for the field):
               element.setProperty(TestElementXYZ.STATE, guiState.getText())
               element.setProperty(TestElementXYZ.CODE, guiCode.getText())
               ... other GUI fields ...
           }

      Specified by:
        `modifyTestElement` in interface `JMeterGUIComponent`
      Parameters:
        `lc` - the TestElement to modify

    - #### clearGui

          public void clearGui()

      Implements JMeterGUIComponent.clearGui
      Specified by:
        `clearGui` in interface `ClearGui`
      Overrides:
        `clearGui` in class `AbstractJMeterGuiComponent`

    - #### actionPerformed

          public void actionPerformed(ActionEvent event)

      Invoked when an action occurs. This implementation assumes that the target component is the infinite loops checkbox.
      Specified by:
        `actionPerformed` in interface `ActionListener`
      Parameters:
        `event` - the event that has occurred

    - #### getLabelResource

          public String getLabelResource()

      Description copied from interface: `JMeterGUIComponent`
      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 overridden in preference to overriding getStaticLabel(). However where the resource name is not available or required, getStaticLabel() may be overridden instead.
      Specified by:
        `getLabelResource` in interface `JMeterGUIComponent`
      Returns:
        the resource name
