    public interface Callable

extends EventListener

`Callable` is used to provide a Service with an interface that supports event calls. Components do not have to implement this interface, though the `onCall` method provides an example lifecycle method that is executed when an event is received for the implementing service.

Method Summary
`Object` | `onCall(MuleEventContext eventContext)` Passes the event to the listener

Method Detail

### onCall

    Object onCall(MuleEventContext eventContext)
                  throws Exception

  Passes the event to the listener

  Parameters:
    `eventContext` - the context of the current event being process
  Returns:
    Object this object can be anything. When the `LifecycleAdapter` for the service receives this object it will first see if the Object is an `MuleMessage` if not and the Object is not null a new message will be created using the returned object as the payload. This new event will then get published via the configured outbound router if-
    1. One has been configured for the component.
    2. the `setStopFurtherProcessing(true)` wasn't called on the event context event.
  Throws:
    `Exception` - if the event fails to process properly. If exceptions aren't handled by the implementation they will be handled by the exceptionListener associated with the service
