Constructor & Destructor Documentation

CConnectionManager::CConnectionManager	(	mrpt::utils::COutputLogger *	logger,
		ros::NodeHandle *	nh_in

Member Function Documentation

bool CConnectionManager::convert	(	const multimaster_msgs_fkie::ROSMaster &	ros_master,
		mrpt_msgs::GraphSlamAgent *	slam_agent
	)		`[static, private]`

ROSMaster ==> mrpt_msgs::GraphSlamAgent.

Assumption is that each ROSMaster instance holds exactly one mrpt_graphslam_2d node which publshes at a specific toic namespace -> /<hostname>_<last_IP_field>/...

Returns:: False if the ros_master specified doesn't correspond to a valid GraphSlamAgent node. Should at least have a feedback topic namespace under its main topic namespace

Definition at line 220 of file CConnectionManager.cpp.

void CConnectionManager::convert	(	const mrpt_msgs::GraphSlamAgent &	slam_agent,
		multimaster_msgs_fkie::ROSMaster *	ros_master
	)		`[static, private]`

GraphSlamAgent ==> ROSMaster.

Definition at line 276 of file CConnectionManager.cpp.

std::string CConnectionManager::extractHostnameOrIP	(	const std::string &	str,
		unsigned short *	agent_port = `NULL`
	)		`[static, private]`

Remove http:// prefix and port suffix from the string and return result.

Parameters:

[out] agent_port Port that the agent is running on. Extracted from the overall string

Definition at line 294 of file CConnectionManager.cpp.

void CConnectionManager::getNearbySlamAgents	(	mrpt_msgs::GraphSlamAgents *	agents_vec,
		bool	ignore_self = `true`
	)

Fill the given vector with the SLAM Agents that the current manager can see and communicate with.

Parameters:

[in] ignore_self If true the GraphSlamAgent instance that is under the same namespace as the CConnectionManager is not going to be inserted in the agents_vec
