Constructor & Destructor Documentation

message_transport::TransportHints::TransportHints	(	const std::string &	default_transport = `"raw"`,
		const ros::TransportHints &	ros_hints = `ros::TransportHints()`,
		const ros::NodeHandle &	parameter_nh = `ros::NodeHandle("~")`,
		const std::string &	parameter_name = `"message_transport"`
	)		`[inline]`

Constructor.

The default transport can be overridden by setting a certain parameter to the name of the desired transport. By default this parameter is named "message_transport" in the node's local namespace. For consistency across ROS applications, the name of this parameter should not be changed without good reason.

Parameters:

default_transport	Preferred transport to use
ros_hints	Hints to pass through to ROS subscriptions
parameter_nh	Node handle to use when looking up the transport parameter. Defaults to the local namespace.
parameter_name	The name of the transport parameter
