__new__()

rosros.rospify.service.Service.__new__	(		cls,
			name,
			service_class,
			handler,
			buff_size = None,
			error_handler = None
	)

Returns rclpy.service.Service instance.

Parameters

name	service name, absolute or relative
service_class	service definition class
handler	callback function for processing service request. Function takes in a ServiceRequest and returns a ServiceResponse of the appropriate type. Function may also return a list, tuple, or dictionary with arguments to initialize a ServiceResponse instance of the correct type. If handler cannot process request, it may either return None, to indicate failure, or it may raise a rospify.ServiceException to send a specific error message to the client. Returning None is always considered a failure.
buff_size	ignored (ROS1 compatibility stand-in)
error_handler	callback function for handling errors raised in the service code, as fn(exception, exception_type, exception_value, traceback)
