...75 * <ul>76 *   <li>if you want to apply the same behavior modification to all methods of77 *   a WebDriver instance and its derived objects you can subclass78 *   WebDriverDecorator and override some of the following methods:79 *   {@link #beforeCall(Decorated, Method, Object[])},80 *   {@link #afterCall(Decorated, Method, Object[], Object)},81 *   {@link #call(Decorated, Method, Object[])} and82 *   {@link #onError(Decorated, Method, Object[], InvocationTargetException)}</li>83 *   <li>if you want to modify behavior of a specific class instances only84 *   (e.g. behaviour of WebElement instances) you can override one of the85 *   overloaded <code>createDecorated</code> methods to create a non-trivial86 *   decorator for the specific class only.</li>87 * </ul>88 * Let's consider both approaches by examples.89 * <p>90 * One of the most widely used decorator examples is a logging decorator.91 * In this case we want to add the same piece of logging code before and after92 * each invoked method:93 * <code>94 *   public class LoggingDecorator extends WebDriverDecorator {95 *     final Logger logger = LoggerFactory.getLogger(Thread.currentThread().getName());96 *97 *     @Override98 *     public void beforeCall(Decorated<?> target, Method method, Object[] args) {99 *       logger.debug("before {}.{}({})", target, method, args);100 *     }101 *     @Override102 *     public void afterCall(Decorated<?> target, Method method, Object[] args, Object res) {103 *       logger.debug("after {}.{}({}) => {}", target, method, args, res);104 *     }105 *   }106 * </code>107 * For the second example let's implement a decorator that implicitly waits108 * for an element to be visible before any click or sendKeys method call.109 * <code>110 *   public class ImplicitlyWaitingDecorator extends WebDriverDecorator {111 *     private WebDriverWait wait;112 *113 *     @Override114 *     public Decorated<WebDriver> createDecorated(WebDriver driver) {115 *       wait = new WebDriverWait(driver, Duration.ofSeconds(10));116 *       return super.createDecorated(driver);117 *     }118 *     @Override119 *     public Decorated<WebElement> createDecorated(WebElement original) {120 *       return new DefaultDecorated<>(original, this) {121 *         @Override122 *         public void beforeCall(Method method, Object[] args) {123 *           String methodName = method.getName();124 *           if ("click".equals(methodName) || "sendKeys".equals(methodName)) {125 *             wait.until(d -> getOriginal().isDisplayed());126 *           }127 *         }128 *       };129 *     }130 *   }131 * </code>132 * This class is not a pure decorator, it allows to not only add new behavior133 * but also replace "normal" behavior of a WebDriver or derived objects.134 * <p>135 * Let's suppose you want to use JavaScript-powered clicks instead of normal136 * ones (yes, this allows to interact with invisible elements, it's a bad137 * practice in general but sometimes it's inevitable). This behavior change138 * can be achieved with the following "decorator":139 * <code>140 *   public class JavaScriptPoweredDecorator extends WebDriverDecorator {141 *     @Override142 *     public Decorated<WebElement> createDecorated(WebElement original) {143 *       return new DefaultDecorated<>(original, this) {144 *         @Override145 *         public Object call(Method method, Object[] args) throws Throwable {146 *           String methodName = method.getName();147 *           if ("click".equals(methodName)) {148 *             JavascriptExecutor executor = (JavascriptExecutor) getDecoratedDriver().getOriginal();149 *             executor.executeScript("arguments[0].click()", getOriginal());150 *             return null;151 *           } else {152 *             return super.call(method, args);153 *           }154 *         }155 *       };156 *     }157 *   }158 * </code>159 * It is possible to apply multiple decorators to compose behaviors added160 * by each of them. For example, if you want to log method calls and161 * implicitly wait for elements visibility you can use two decorators:162 * <code>163 *   WebDriver original = new FirefoxDriver();164 *   WebDriver decorated =165 *     new ImplicitlyWaitingDecorator().decorate(166 *       new LoggingDecorator().decorate(original));167 * </code>168 */169@Beta170public class WebDriverDecorator {171  private
