java.lang.Class<? extends ExtensionHandler> value
```
    ExtensionHandler factory annotation that creates the extension handler for the decorated method.
    The extension handler must have either a public no-arguments, a (Method method), or a (Class<?> extensionType, Method method) constructor. If the constructor takes one or more arguments, it will get the extension type and the invoked method passed in at construction time.
    
    Returns:
    
    the ExtensionHandler class
- - id
```
java.lang.String id
```
    An extension must declare an id and tag all annotations with it. This allows the ExtensionFactory to decide whether it will process a class or not by looking at the annotations on the class and method and determine whether these have the right id for the extension.
    
    Returns:
    
    A string with the extension identifier
