const geometry_msgs::Pose2D & dwb_local_planner::getClosestPose	(	const dwb_msgs::Trajectory2D &	trajectory,
		const double	time_offset
	)

Helper function to find a pose in the trajectory with a particular time time_offset.

Parameters

trajectory	The trajectory to search
time_offset	The desired time_offset

Returns

reference to the pose that is closest to the particular time offset

Linearly searches through the poses. Once the poses time_offset is greater than the desired time_offset, the search ends, since the poses have increasing time_offsets.

void dwb_local_planner::loadBackwardsCompatibleParameters

(

const ros::NodeHandle &

nh

)

Load parameters to emulate dwa_local_planner.

If no critic parameters are specified, this function should be called to load/move parameters that will emulate the behavior of dwa_local_planner

Parameters

nh	NodeHandle to load parameters from

geometry_msgs::Pose2D dwb_local_planner::projectPose	(	const dwb_msgs::Trajectory2D &	trajectory,
		const double	time_offset
	)

Helper function to create a pose with an exact time_offset by linearly interpolating between existing poses.

Parameters

trajectory	The trajectory with pose and time offset information
time_offset	The desired time_offset

Returns

New Pose2D with interpolated values

Note

If the given time offset is outside the bounds of the trajectory, the return pose will be either the first or last pose.
