Constructor & Destructor Documentation

template<typename T >

rtt_roscomm::RosPubChannelElement< T >::RosPubChannelElement	(	base::PortInterface *	port,
		const ConnPolicy &	policy
	)		[inline]

Contructor of to create ROS publisher ChannelElement, it will create a topic from the name given by the policy.name_id, if this is empty a default is created as hostname/componentname/portname/pid

Parameters:

port	port for which we will create a the ROS publisher
policy	connection policy containing the topic name and buffer size

Returns:

ChannelElement that will publish data to topics
