\fB0\fP : first horizontal (\fBh1\fP)\&.

Not all the indexes are filled for every \fBAutoContact\fP\&. For example \fCTurn\fP have \fBh1\fP and \fBb1\fP, and \fCHTee\fP have \fBh1\fP, \fBh2\fP and \fBv1\fP\&.

Compute the new position of the \fBAutoContact\fP based on the \fBAutoSegment\fP positions\&. The \fBSession\fP mechanism ensure that all \fBAutoSegment\fP are set into their final positions before calling this updator\&.

.SS "void updateTopology ()\fC [virtual]\fP"
|
|
Restore the topology (i\&.e\&. connexity) of the contact after any number of connected segments has changed layer (at least one, up to three)\&.
|
|
.PP
|
|
For any configuration, the connexity can be restored by making only one dogleg\&.
|
|
.PP
|
|
We distinguish two kind of layer changes:
|
|
.IP "1." 4
|
|
The two horizontals (\fCh1\fP and \fCh2\fP) are still on the same layer (either they both moved or the vertical only has moved, see figures 2 & 4)\&. In that case, the dogleg is made on the vertical\&.
|
|
.IP "2." 4
|
|
The two horizontals no longer are on the same layer (figures 1 & 3)\&. In that case, the dogleg is made on the horizontal which is at the greater distance (in a layer sense) from the vertical\&.
