Method Detail

### asynchronousServiceHandle

    public DataObject asynchronousServiceHandle(java.lang.String requestTag,
                                                DataObject data)
                                         throws InvalidMethodException,
                                                MethodException

  This abstract method is used to generically handle the results from any asynchronous service that a widget may support. An asynchronous service will trigger this method to be called when the object implementing this interface calls the remote asynchronous service.
  Parameters:
    `requestTag` - The requestTag used to identify the service request
    `data` - DataObject containing the data for service execution
  Returns:
    DataObject containing any directives to the service that was executed
  Throws:
    InvalidMethodException - if the specified callback can't be found
    MethodException - is thrown if the specified callback can not be executed successfully
