Class GuiPackage

java.lang.Object
  extended byorg.apache.jmeter.gui.GuiPackage
All Implemented Interfaces:
LocaleChangeListener

public final class GuiPackage
extends Object
implements LocaleChangeListener

GuiPackage is a static class that provides convenient access to information about the current state of JMeter's GUI. Any GUI class can grab a handle to GuiPackage by calling the static method getInstance() and then use it to query the GUI about it's state. When actions, for instance, need to affect the GUI, they typically use GuiPackage to get access to different parts of the GUI.

Method Detail

getInstance

public static GuiPackage getInstance()
Retrieve the singleton GuiPackage instance.

Returns:
the GuiPackage instance

getInstance

public static GuiPackage getInstance(JMeterTreeListener listener,
                                     JMeterTreeModel treeModel)
When GuiPackage is requested for the first time, it should be given handles to JMeter's Tree Listener and TreeModel.

Parameters:
listener - the TreeListener for JMeter's test tree
treeModel - the model for JMeter's test tree
Returns:
GuiPackage

getGui

public JMeterGUIComponent getGui(TestElement node)
Get a JMeterGUIComponent for the specified test element. If the GUI has already been created, that instance will be returned. Otherwise, if a GUI component of the same type has been created, and the component is not marked as an UnsharedComponent, that shared component will be returned. Otherwise, a new instance of the component will be created. The TestElement's GUI_CLASS property will be used to determine the appropriate type of GUI component to use.

Parameters:
node - the test element which this GUI is being created for
Returns:
the GUI component corresponding to the specified test element

getGui

public JMeterGUIComponent getGui(TestElement node,
                                 Class guiClass,
                                 Class testClass)
Get a JMeterGUIComponent for the specified test element. If the GUI has already been created, that instance will be returned. Otherwise, if a GUI component of the same type has been created, and the component is not marked as an UnsharedComponent, that shared component will be returned. Otherwise, a new instance of the component will be created.

Parameters:
node - the test element which this GUI is being created for
guiClass - the fully qualifed class name of the GUI component which will be created if it doesn't already exist
testClass - the fully qualifed class name of the test elements which have to be edited by the returned GUI component
Returns:
the GUI component corresponding to the specified test element

removeNode

public void removeNode(TestElement node)
Remove a test element from the tree. This removes the reference to any associated GUI component.

Parameters:
node - the test element being removed

getCurrentGui

public JMeterGUIComponent getCurrentGui()
Convenience method for grabbing the gui for the current node.

Returns:
the GUI component associated with the currently selected node

getNodeOf

public JMeterTreeNode getNodeOf(TestElement userObject)
Find the JMeterTreeNode for a certain TestElement object.

Parameters:
userObject - the test element to search for
Returns:
the tree node associated with the test element

createTestElement

public TestElement createTestElement(Class guiClass,
                                     Class testClass)
Create a TestElement corresponding to the specified GUI class.

Parameters:
guiClass - the fully qualified class name of the GUI component or a TestBean class for TestBeanGUIs.
testClass - the fully qualified class name of the test elements edited by this GUI component.
Returns:
the test element corresponding to the specified GUI class.

createTestElement

public TestElement createTestElement(String objClass)
Create a TestElement for a GUI or TestBean class.

This is a utility method to help actions do with one single String parameter.

Parameters:
objClass - the fully qualified class name of the GUI component or of the TestBean subclass for which a TestBeanGUI is wanted.
Returns:
the test element corresponding to the specified GUI class.

setDirty

public void setDirty(boolean dirty)
The dirty property is a flag that indicates whether there are parts of JMeter's test tree that the user has not saved since last modification. Various (@link Command actions) set this property when components are modified/created/saved.

Parameters:
dirty - the new value of the dirty flag

isDirty

public boolean isDirty()
Retrieves the state of the 'dirty' property, a flag that indicates if there are test tree components that have been modified since they were last saved.
