Detailed Description

A segment feature, with its extremities.

The extremities are not represented in a stochastic way, they are expressed in the 1-dimenssion frame defined by the segment representation (s,u).

Member Function Documentation

virtual void jafar::slam::SegmentFeature::setState	(	jblas::vec &	x_,
		jblas::sym_mat &	P_
	)		[virtual]

Set object's state vector and covariance.

Parameters:

x_	state vector
P_	covariances matrix

Reimplemented from jafar::slam::AbstractMapObject.

virtual void jafar::slam::SegmentFeature::writeLogData

(

jafar::kernel::DataLogger &

log

)

const [protected, virtual]

Implements this method calling repeatidly log methods.

You should use writeData() or writeDataVector().

Reimplemented from jafar::slam::BaseFeature.
