```
    Returns a List of strings naming the files and directories in the directory denoted by this abstract pathname.
    
    If this abstract pathname does not denote a directory, or does not exist, then this method throws ResourceDoesNotExistException. Otherwise a List of strings is returned, one for each file or directory in the directory. Names denoting the directory itself and the directory's parent directory are not included in the result. Each string is a file name rather than a complete path.
    
    There is no guarantee that the name strings in the resulting list will appear in any specific order; they are not, in particular, guaranteed to appear in alphabetical order.
    
    Parameters:
    destinationDirectory - directory to list contents of
    
    Returns:
    A List of strings naming the files and directories in the directory denoted by this abstract pathname. The List will be empty if the directory is empty.
    
    Throws:
    
    TransferFailedException - if there's an error trying to access the remote side
    
    ResourceDoesNotExistException - if destinationDirectory does not exist or is not a directory
    
    AuthorizationException - if not authorized to list the contents of the directory
