<P>
This is the base class for JMeter GUI components which can display test
 results in some way. It provides the following conveniences to developers:
 <ul>
 <li>Implements the
 <A HREF="../../../../../org/apache/jmeter/gui/JMeterGUIComponent.html" title="interface in org.apache.jmeter.gui"><CODE>JMeterGUIComponent</CODE></A> interface
 that allows your Gui visualizer to "plug-in" to the JMeter GUI environment.
 Provides implementations for the following methods:
 <ul>
 <li><A HREF="../../../../../org/apache/jmeter/gui/JMeterGUIComponent.html#configure(org.apache.jmeter.testelement.TestElement)"><CODE>configure(TestElement)</CODE></A>.
 Any additional parameters of your Visualizer need to be handled by you.</li>
 <li><A HREF="../../../../../org/apache/jmeter/gui/JMeterGUIComponent.html#createTestElement()"><CODE>createTestElement()</CODE></A>.
 For most purposes, the default
 <A HREF="../../../../../org/apache/jmeter/reporters/ResultCollector.html" title="class in org.apache.jmeter.reporters"><CODE>ResultCollector</CODE></A> created
 by this method is sufficient.</li>
 <li><A HREF="../../../../../org/apache/jmeter/gui/JMeterGUIComponent.html#getMenuCategories()"><CODE>getMenuCategories()</CODE></A>.
 To control where in the GUI your visualizer can be added.</li>
 <li><A HREF="../../../../../org/apache/jmeter/gui/JMeterGUIComponent.html#modifyTestElement(org.apache.jmeter.testelement.TestElement)"><CODE>modifyTestElement(TestElement)</CODE></A>.
 Again, additional parameters you require have to be handled by you.</li>
 <li><A HREF="../../../../../org/apache/jmeter/gui/JMeterGUIComponent.html#createPopupMenu()"><CODE>createPopupMenu()</CODE></A>.</li>
 </ul>
 </li>
 <li>Provides convenience methods to help you make a JMeter-compatible GUI:
 <ul>
 <li><A HREF="../../../../../org/apache/jmeter/visualizers/gui/AbstractVisualizer.html#makeTitlePanel()"><CODE>makeTitlePanel()</CODE></A>. Returns a panel that includes the name of
 the component, and a FilePanel that allows users to control what file samples
 are logged to.</li>
 <li><A HREF="../../../../../org/apache/jmeter/visualizers/gui/AbstractVisualizer.html#getModel()"><CODE>getModel()</CODE></A> and <A HREF="../../../../../org/apache/jmeter/visualizers/gui/AbstractVisualizer.html#setModel(org.apache.jmeter.reporters.ResultCollector)"><CODE>setModel(ResultCollector)</CODE></A> methods for
 setting and getting the model class that handles the receiving and logging of
 sample results.</li>
 </ul>
 </li>
 </ul>
 For most developers, making a new visualizer is primarly for the purpose of
 either calculating new statistics on the sample results that other
 visualizers don't calculate, or displaying the results visually in a new and
 interesting way. Making a new visualizer for either of these purposes is easy -
 just extend this class and implement the
 <A HREF="../../../../../org/apache/jmeter/visualizers/Visualizer.html#add(org.apache.jmeter.samplers.SampleResult)"><CODE>add(SampleResult)</CODE></A>
 method and display the results as you see fit. This AbstractVisualizer and
 the default
 <A HREF="../../../../../org/apache/jmeter/reporters/ResultCollector.html" title="class in org.apache.jmeter.reporters"><CODE>ResultCollector</CODE></A> handle
 logging and registering to receive SampleEvents for you - all you need to do
 is include the JPanel created by makeTitlePanel somewhere in your gui to
 allow users set the log file.
 <p>
 If you are doing more than that, you may need to extend
 <A HREF="../../../../../org/apache/jmeter/reporters/ResultCollector.html" title="class in org.apache.jmeter.reporters"><CODE>ResultCollector</CODE></A> as well
 and modify the <A HREF="../../../../../org/apache/jmeter/visualizers/gui/AbstractVisualizer.html#configure(org.apache.jmeter.testelement.TestElement)"><CODE>configure(TestElement)</CODE></A>,
 <A HREF="../../../../../org/apache/jmeter/visualizers/gui/AbstractVisualizer.html#modifyTestElement(org.apache.jmeter.testelement.TestElement)"><CODE>modifyTestElement(TestElement)</CODE></A>, and <A HREF="../../../../../org/apache/jmeter/visualizers/gui/AbstractVisualizer.html#createTestElement()"><CODE>createTestElement()</CODE></A>
 methods to create and modify your alternate ResultCollector. For an example
 of this, see the
 <A HREF="../../../../../org/apache/jmeter/visualizers/MailerVisualizer.html" title="class in org.apache.jmeter.visualizers"><CODE>MailerVisualizer</CODE></A>.
