    • getNameField

    • clearGui

      public void clearGui()
      Description copied from interface: 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 uses.
      Specified by:
      clearGui in interface ClearGui

    • getName

      public String getName()
      Get the currently displayed name.
      Specified by:
      getName in interface JMeterGUIComponent
      Overrides:
      getName in class Component
      Returns:
      the current name

    • setName

      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.
      Specified by:
      setName in interface JMeterGUIComponent
      Overrides:
      setName in class Component
      Parameters:
      name - the name of the component

    • configure

      public void configure(org.apache.jmeter.testelement.TestElement testElement)
      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.

      The canonical implementation looks like this: 

       public void configure(TestElement element) {
     super.configure(element);
     // Using the element getter (preferred):
     TestElementXYZ xyz = (TestElementXYZ) element;
     guiState.setText(xyz.getState());
     guiCode.setText(xyz.getCode());
     ... other GUI fields ...
     // or using the element property names directly (do not use unless there is no getter for the field)
     guiState.setText(element.getPropertyAsString(TestElementXYZ.STATE));
     guiCode.setText(element.getPropertyAsString(TestElementXYZ.CODE));
     ... other GUI fields ...
 }
      Specified by:
      configure in interface JMeterGUIComponent
      Parameters:
      testElement - the TestElement to configure

    • createPopupMenu

      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.
      Specified by:
      createPopupMenu in interface JMeterGUIComponent
      Returns:
      a JPopupMenu appropriate for the component.

    • getStaticLabel

      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.
      Specified by:
      getStaticLabel in interface JMeterGUIComponent
      Returns:
      GUI label for the component.
      See Also:

    • getLabelResource

      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 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

    • getMenuCategories

      public Collection<String> 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.
      Specified by:
      getMenuCategories in interface JMeterGUIComponent
      Returns:
      a Collection of Strings, where each element is one of the constants defined in MenuFactory
      See Also:

    • createTestElement

      public org.apache.jmeter.testelement.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.

      Since 5.6.3, the default implementation is as follows, and subclasses should override JMeterGUIComponent.makeTestElement() 

       public TestElement createTestElement() {
     TestElement element = makeTestElement();
     assignDefaultValues(element);
     return el;
 }

      Before 5.6.3 the canonical implementation was as follows, however, it is recommended to avoid overriding JMeterGUIComponent.createTestElement() and override JMeterGUIComponent.makeTestElement() instead. 

       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(org.apache.jmeter.testelement.TestElement wb)
      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.

      If you override AbstractJMeterGuiComponent, you might want using AbstractJMeterGuiComponent.bindingGroup instead of overriding modifyTestElement.

      The canonical implementation looks like this: 

       @Override
 public void modifyTestElement(TestElement element) {
     super.modifyTestElement(element); // clear the element and assign basic fields like name, gui class, test class
     // Using the element setters (preferred):
     // If the field is empty, you probably want to remove the property instead of storing an empty string
     // See Streamline binding of UI elements to TestElement properties
     // for more details
     TestElementXYZ xyz = (TestElementXYZ) element;
     xyz.setState(StringUtils.defaultIfEmpty(guiState.getText(), null));
     xyz.setCode(StringUtils.defaultIfEmpty(guiCode.getText(), null));
     ... other GUI fields ...
     // or directly (do not use unless there is no setter for the field):
     element.setProperty(TestElementXYZ.STATE, StringUtils.defaultIfEmpty(guiState.getText(), null))
     element.setProperty(TestElementXYZ.CODE, StringUtils.defaultIfEmpty(guiCode.getText(), null))
     ... other GUI fields ...
 }
      Specified by:
      modifyTestElement in interface JMeterGUIComponent
      Parameters:
      wb - the TestElement to modify

    • getDocAnchor

      public String getDocAnchor()
      Get the component's document anchor name. Used by Help to find the appropriate location in the documentation
      Specified by:
      getDocAnchor in interface JMeterGUIComponent
      Returns:
      Document anchor (#ref) for the component.
