 /**
 24  
  * The BridgeComponent is a standard Mule component that enables a bridge between an inbound and outbound endpoints.
 25  
  * Transformers can be used on the endpoints to convert the data being received in order to 'bridge' from one
 26  
  * endpoint transport to another.  When the BridgeComponent is used, it configures itself so that it will
 27  
  * not actually be invoked, instead it tells Mule to bypass invocation of the component, which has a slight performance
 28  
  * improvement. Note that because the component is never actually invoked any interceptors configured on the component
 29  
  * will not be invoked either.
