Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`String`	`handleError(Actor source, String type, String msg)`	Handles the given error message with the flow that the actor belongs to, if the flow has error logging turned on.

- Method Detail
  - handleError
```
String handleError(Actor source,
                   String type,
                   String msg)
```
    Handles the given error message with the flow that the actor belongs to, if the flow has error logging turned on. Might stop the flow as well.
    
    Parameters:
    
    source - the actor this error originated from
    
    type - the type of error
    
    msg - the error message to log
    
    Returns:
    
    null if error has been handled, otherwise the error message
    
    See Also:
