Mechanism used to locate elements within a document. In order to create your own locating mechanisms, it is possible to subclass this class and override the protected methods as required, though it is expected that all subclasses rely on the basic finding mechanisms provided through static methods of this class:
 public WebElement findElement(WebDriver driver) {     WebElement element = driver.findElement(By.id(getSelector()));     if (element == null)       element = driver.findElement(By.name(getSelector());     return element; }
