    Description copied from interface: DiscoverySelector
    
    Return the identifier of this selector.
    The returned identifier must be parsable by a corresponding DiscoverySelectorIdentifierParser.
    The default implementation returns Optional.empty(). Can be overridden by concrete implementations.
    
    Specified by:
    
    toIdentifier in interface DiscoverySelector
    
    Returns:
    
    an Optional containing the identifier of this selector; never null but potentially empty if the selector does not support identifiers
