Member Function Documentation

bool laser_filters::LaserArrayFilter::configure

(

)

[virtual]

Implements filters::FilterBase< sensor_msgs::LaserScan >.

Definition at line 41 of file array_filter.cpp.

bool laser_filters::LaserArrayFilter::update	(	const sensor_msgs::LaserScan &	scan_in,
		sensor_msgs::LaserScan &	scan_out
	)		[virtual]

Update the filter and get the response.

Parameters:

scan_in	The new scan to filter
scan_out	The filtered scan

Quickly pass through all data

Todo:

don't copy data too

Todo:

check for length of intensities too
