Constructor & Destructor Documentation

tf::MessageFilterJointState::MessageFilterJointState	(	Transformer &	tf,
		const std::string &	target_frame,
		uint32_t	queue_size,
		ros::NodeHandle	nh = `ros::NodeHandle()`,
		ros::Duration	max_rate = `ros::Duration(0.01)`
	)		`[inline]`

Constructor.

Parameters:

tf	The tf::Transformer this filter should use
target_frame	The frame this filter should attempt to transform to. To use multiple frames, pass an empty string here and use the setTargetFrames() function.
queue_size	The number of messages to queue up before throwing away old ones. 0 means infinite (dangerous).
nh	The NodeHandle to use for any necessary operations
max_rate	The maximum rate to check for newly transformable messages

Constructor.

Parameters:

f	The filter to connect this filter's input to. Often will be a message_filters::Subscriber.
tf	The tf::Transformer this filter should use
target_frame	The frame this filter should attempt to transform to. To use multiple frames, pass an empty string here and use the setTargetFrames() function.
queue_size	The number of messages to queue up before throwing away old ones. 0 means infinite (dangerous).
