We use an array of {\itshape regularly spaced}\hyperlink{classKite_1_1Track}{Track} as a geometrical fast access structure. It allows to know whether an area is used or not. The whole area may be seen as a set of adjoining tiles of fixed {\itshape width} but variable {\itshape length}.
The figure {\bfseries (1.\-b)} show, for an horizontal, track the relation between {\ttfamily y,min,max} and the occupied area of the plane. {\ttfamily min} and {\ttfamily max} must take into account segment extensions ({\ttfamily e}) and the minimal distance between two rectangles ({\ttfamily M\-D}) of the same layer. We assume that the width of the segment, augmented of all it's contraints is no greater than {\ttfamily T\-S} (in fact it's how {\ttfamily T\-S} must be calculated).
A \hyperlink{classKite_1_1Track}{Track} is implemented with a sorted vector of \hyperlink{classKite_1_1TrackElement}{Track\-Element}. Track\-Elements from differents nets must not overlap. The sorting order is defined as follow\-:
\item Track\-Elements are sorted by increasing source ({\itshape min}) positions.
\item In case of overlap (i.\-e. belongs to the same net), if they share the same source position, then they are sorted by {\itshape decreasing} length. This way, the longest one will be the first encountered when walking through the \hyperlink{classKite_1_1Track}{Track} in increasing index order.
Figure {\bfseries 2.\-b} shows the details of the \hyperlink{classKite_1_1Track}{Track}{\bfseries\mbox{[}1\mbox{]}} of figure {\bfseries 1.\-a}. Net {\bfseries$<$d$>$} show an exemple of overlapping.
In addition to the Track\-Segments, the \hyperlink{classKite_1_1Track}{Track} also manage additionnal informations through a second vector of Track\-Markers. \hyperlink{classKite_1_1TrackMarker}{Track\-Marker} are currently used only to hints at how strongly a terminal is dependant on that portion of \hyperlink{classKite_1_1Track}{Track} to be accessed.\hypertarget{classKite_1_1Track_ssecTrackIndexes}{}\paragraph{Indexes vs. Iterators}\label{classKite_1_1Track_ssecTrackIndexes}
Numerical indexes have been prefered over iterators because they can be used more easily by objects other the \hyperlink{classKite_1_1Track}{Track} itself for referencing. So internal managment follow the same rule, handling indexes or reference to indexes.\hypertarget{classKite_1_1Track_ssecTrackUpdate}{}\paragraph{Update Mechanism}\label{classKite_1_1Track_ssecTrackUpdate}
When a \hyperlink{classKite_1_1TrackElement}{Track\-Element} is normaly inserted in a \hyperlink{classKite_1_1Track}{Track}, a two way link is established. The \hyperlink{classKite_1_1Track}{Track} has an entry in it's vector refering to \hyperlink{classKite_1_1TrackElement}{Track\-Element}, and conversely, the \hyperlink{classKite_1_1TrackElement}{Track\-Element} has it's {\ttfamily track} field pointing to it's owning \hyperlink{classKite_1_1Track}{Track}.
To remove a \hyperlink{classKite_1_1TrackElement}{Track\-Element} from a \hyperlink{classKite_1_1Track}{Track}, we break one of those two links\-: the \hyperlink{classKite_1_1TrackElement}{Track\-Element} cease to refer to the owning \hyperlink{classKite_1_1Track}{Track}, marking him for removal which will occurs at the next track revalidation (\hyperlink{classKite_1_1Track_abfffcd781865b94f62f27a1e7be99a38}{Track\-::do\-Removal()}). In figure {\bfseries 3}, the \hyperlink{classKite_1_1TrackElement}{Track\-Element} belonging to net {\bfseries$<$b$>$} is marked for removal.
When a \hyperlink{classKite_1_1TrackElement}{Track\-Element} is inserted into a \hyperlink{classKite_1_1Track}{Track}, the two way link is immediatly created (but the \hyperlink{classKite_1_1TrackElement}{Track\-Element} is not yet at it's final place in the \hyperlink{classKite_1_1Track}{Track}'s vector). Before inserting a \hyperlink{classKite_1_1TrackElement}{Track\-Element} we check that it's been already detached ({\ttfamily track} field to {\ttfamily N\-U\-L\-L}).
It is at that step that the \hyperlink{classKite_1_1TrackElement}{Track\-Element} axis is actually updated through a call to \hyperlink{classKite_1_1TrackElement_a45e685b1e3ee630d24bf43746553af4c}{Track\-Element\-::set\-Axis()}.
After a \hyperlink{classKite_1_1Track}{Track} has been modificated either the \hyperlink{classKite_1_1Track}{Track} element vector or the Marker\-Element vector (or both) has been invalidateds. Revalidation take place in three steps\-:
\item\hyperlink{classKite_1_1Track_abfffcd781865b94f62f27a1e7be99a38}{Track\-::do\-Removal()}, remove all \hyperlink{classKite_1_1TrackElement}{Track\-Element} marked for removal.
\item\hyperlink{classKite_1_1Track_aa392ba7cf1e3e485aac11cf326e31918}{Track\-::insert()}, insert the \hyperlink{classKite_1_1TrackElement}{Track\-Element} into their new \hyperlink{classKite_1_1Track}{Track}.
\item\hyperlink{classKite_1_1Track_aaccb9224f5b38ecd8506fd1eec9ef5ca}{Track\-::do\-Reorder()}, sort the \hyperlink{classKite_1_1TrackElement}{Track\-Element} of the vector, that is, put the newly inserted elements at their right place.
Each step must be done {\itshape for all Tracks} before proceeding to the next. This way a \hyperlink{classKite_1_1TrackElement}{Track\-Element}{\ttfamily track} field doesn't get set {\itshape before} it has been actually removed from it's previous \hyperlink{classKite_1_1Track}{Track}.\hypertarget{classKite_1_1Track_ssecTrackOperations}{}\paragraph{Main Operations on Tracks}\label{classKite_1_1Track_ssecTrackOperations}

Suppress all the \hyperlink{classKite_1_1TrackSegment}{Track\-Segment} that have been withdraw from the \hyperlink{classKite_1_1Track}{Track}. \hyperlink{classKite_1_1TrackSegment}{Track\-Segment} must be withdraw trough the \hyperlink{classKite_1_1TrackSegment_ac295bade8aee589f6718dfa79edc2a34}{Track\-Segment\-::detach()} method which sets their owning \hyperlink{classKite_1_1Track}{Track} to {\ttfamily N\-U\-L\-L} (the removal criterion). It uses the \href{http://www.sgi.com/tech/stl/}{\tt S\-T\-L}{\itshape remove\-\_\-if} algorithm that put all the to be removed elements at the end of the vector.
