  - as
```
public static Element as(JavaScriptObject o)
```
    Assert that the given Node is an Element and automatically typecast it.
  - as
```
public static Element as(Node node)
```
    Assert that the given Node is an Element and automatically typecast it.
  - is
```
public static boolean is(JavaScriptObject o)
```
    Determines whether the given JavaScriptObject can be cast to an Element. A null object will cause this method to return false.
  - is
```
public static boolean is(Node node)
```
    Determine whether the given Node can be cast to an Element. A null node will cause this method to return false.
  - addClassName
```
public final boolean addClassName(String className)
```
    Adds a name to this element's class property. If the name is already present, this method has no effect.
    
    Parameters:
    
    className - the class name to be added
    
    Returns:
    
    true if this element did not already have the specified class name
    
    See Also:
    
    setClassName(String)
  - blur
```
public final void blur()
```
    Removes keyboard focus from this element.
  - dispatchEvent
```
public final void dispatchEvent(NativeEvent evt)
```
    Dispatched the given event with this element as its target. The event will go through all phases of the browser's normal event dispatch mechanism. Note: Because the browser's normal dispatch mechanism is used, exceptions thrown from within handlers triggered by this method cannot be caught by wrapping this method in a try/catch block. Such exceptions will be caught by the uncaught exception handler as usual.
    
    Parameters:
    
    evt - the event to be dispatched

  - getClassName
```
public final String getClassName()
```
    The class attribute of the element. This attribute has been renamed due to conflicts with the "class" keyword exposed by many languages.
