- Method Detail
  - transformComponentEventLink
```
Link transformComponentEventLink(Link defaultLink,
                                 ComponentEventRequestParameters parameters)
```
    Allows the default Link created for the component event request to be replaced.
    
    Parameters:
    
    defaultLink - the default Link generated for a component event request
    
    parameters - used to create the default Link
    
    Returns:
    
    a replacement Link, or null
  - decodeComponentEventRequest
```
ComponentEventRequestParameters decodeComponentEventRequest(Request request)
```
    Attempts to decode the page render request, to perform the opposite action for transformComponentEventLink(Link, ComponentEventRequestParameters). The transformer is also responsible for identifying the locale in the request (as part of the path, or as a query parameter or cookie) and setting the locale for the request. This method will be invoked from the ComponentEventDispatcher and a non-null value returned from this method will prevent the default ComponentEventLinkEncoder.decodeComponentEventRequest(Request) method from being invoked.
    
    Returns:
    
    decoded parameters, or null to proceed normally
