 * JMeter GUI element editing for TestBean elements.

* The actual GUI is always a bean customizer: if the bean descriptor provides * one, it will be used; otherwise, a GenericTestBeanCustomizer will be * created for this purpose. *

* Those customizers deviate from the standards only in that, instead of a * bean, they will receive a Map in the setObject call. This will be a property * name to value Map. The customizer is also in charge of initializing empty * Maps with sensible initial values. *

* If the provided Customizer class implements the SharedCustomizer * interface, the same instance of the customizer will be reused for all * beans of the type: setObject(map) can then be called multiple times. * Otherwise, one separate instance will be used for each element. * For efficiency reasons, most customizers should implement * SharedCustomizer. * * @version $Revision: 1.14 $ updated on $Date: 2004/03/05 01:46:12 $ */ public class TestBeanGUI extends AbstractJMeterGuiComponent implements JMeterGUIComponent { private static Logger log = LoggingManager.getLoggerForClass(); private Class testBeanClass; private BeanInfo beanInfo; private Class customizerClass; /** * The single customizer if the customizer class implements * SharedCustomizer, null otherwise. */ private Customizer customizer= null; /** * TestElement to Customizer map if customizer is null.
