Detailed Description

Action server for the actionlib-based implementation of tf2_ros::BufferInterface.

Use this class with a tf2_ros::TransformListener in the same process. You can use this class with a tf2_ros::BufferClient in a different process.

Constructor & Destructor Documentation

tf2_ros::BufferServer::BufferServer	(	const Buffer &	buffer,
		const std::string &	ns,
		bool	auto_start = true,
		ros::Duration	check_period = ros::Duration(0.01)
	)

Constructor.

Parameters:

buffer	The Buffer that this BufferServer will wrap.
ns	The namespace in which to look for action clients.
auto_start	Pass argument to the constructor of the ActionServer.
check_period	How often to check for changes to known transforms (via a timer event).
