The \hyperlink{classKite_1_1DataNegociate}{Data\-Negociate} object contains all the informations the negociation algorithm needs to know about a \hyperlink{classKite_1_1TrackSegment}{Track\-Segment}. Those informations mostly describe the slackening and ripup state of that segment.
\item The slackening state (see \hyperlink{classKite_1_1DataNegociate_ab7ccb6fc1f298728995250a3bbcf18c7}{Data\-Negociate\-::\-Slack\-State}). The state indicate the {\bfseries next} topological modification to be applied on the segment should the ripup count reach it's maximal value.
\item The associated \hyperlink{classKite_1_1RoutingEvent}{Routing\-Event}. If no \hyperlink{classKite_1_1RoutingEvent}{Routing\-Event} is present, it means the segment has been either successufully placed or the algorithm has given up trying to. If present, it is a {\itshape pending} request for placement.
\item{\ttfamily left\-Min\-Extend}, the potential minimal position of the segment left extension. May not be reachable due to other topological constraints.
\item{\ttfamily right\-Min\-Extend}, the potential minimal position of the segment right extension.
\item{\ttfamily terminals}, the number of terminals attached to this segment.
\item{\ttfamily attractors}, a table of coordinates of the end points of the perpandiculars to this segment. Used to compute the wiring delta if we move the axis of the segment.
\item{\ttfamily perpandiculars}, a {\ttfamily vector} of the perpandicular \hyperlink{classKite_1_1TrackElement}{Track\-Element}. This is a fast-\/access cache. It must be updated each time the topology of the net is modificated.
\item{\ttfamily perpandicular\-Free}, the free interval defined by the perpandiculars, that is for the sgement axis.
All those informations are computed and updated by the \hyperlink{classKite_1_1DataNegociate_ac5c54df7ed3b930268c8d7752c101725}{Data\-Negociate\-::update()} method, which relies on\-:
For every perpandicular set of Auto\-Segment to the \hyperlink{classKite_1_1TrackSegment}{Track\-Segment} we want to place, get the coordinates of the extremity not connected to the segment and put that coordinate into a table associated with it's {\itshape spin}. The {\itshape spin} tells if the extremity is attracting the segment {\itshape up} or {\itshape down} (for an horizontal segment). The {\itshape spin} is incremented for up and decremented for down. After all the extremities have been processeds, we took into account only the coordinates with a non-\/zero spin, which means they truly attract the segment (whatever the direction).
\item Suppress the {\ttfamily Slack\-State\-::\-Desalignate}, due to the simplificated structure of the Auto\-Segment/\-Auto\-Contacts (no more collapseds, or forced alignements).
