handle_smart_get_attributes
Description:
public virtual signal bool handle_smart_get_attributes (DBusMethodInvocation invocation, Variant arg_options)
  
  Signal emitted when a remote caller is invoking the SmartGetAttributes D-Bus method.
If a signal handler returns true, it means the signal handler will handle the invocation (e.g. take a reference to 
        invocation and eventually call 
        complete_smart_get_attributes or e.g. return_error on
      it) and no order signal handlers will run. If no signal handler handles the invocation, the 
      UNKNOWN_METHOD error is returned.
Parameters:
| invocation | |
| arg_options | 
           Argument passed by remote caller.  | 
      
Returns:
