Member Function Documentation

__new__()

rosros.rospify.topics.Publisher.__new__	(		cls,
			name,
			data_class,
			subscriber_listener = None,
			tcp_nodelay = None,
			latch = False,
			headers = None,
			queue_size = None
	)

Constructor.

Parameters

name	resource name of topic, e.g. 'laser'.
data_class	message class for serialization
subscriber_listener	ignored (ROS1 compatibility stand-in)
tcp_nodelay	ignored (ROS1 compatibility stand-in)
latch	if True, the last message published is 'latched', meaning that any compatible subscribers will be sent that message immediately upon connection
headers	ignored (ROS1 compatibility stand-in)
queue_size	the queue size used for asynchronously publishing messages from different threads. A size of zero means an infinite queue, which can be dangerous. When the keyword is not being used or when None is passed, all publishing will happen synchronously and a warning message will be printed.
