Figure 176:
Switchover of segments
Effects at sequence change
In
two cases are described. The original curve is shown in black and exists
of the segments 0-7. The user tries to replace the segments 1-6 by means of a sequence
change of the segments 8-13 (red partial curve). In
times are shown for this switching procedure. The content of the intermediate buffer is
indicated by the colored bars below the coordinate system.
This means that the interim buffering contains the segments 5 to 7 and 0 to 3 if the seg-
ment 0 is active when switching over. The reason is that the active segment, the three
previous segments and the three following segments are provided.
At the switchover point the new interlinking is accepted including all of its curve segments.
The interim buffering still remains unchanged. The predecessors and the successors are
updated in the interim buffering after the next segment change.
In the example the active segment 0 is processed during a positive master direction and
then it jumps to segment 1. Then at the change in segment 1 the followers of segment 1
are updated in the interim buffering and an interlinking change comes into effect. As the
interlinking change applies to segment 0 (change of 0
1 to 0
8) and segment 1 now
is active the interlinking change is not made in this passage. Once more the black curve
is passed. At the next passage after segment 0 the branching to segment 8 is made and
the red curve is processed.
In the second case the switchover (red) is already initiated in segment 7.
During this point the segments 4 to 7 and 0 to 2 are in the interim buffering. At the next
segment change the interim buffering with its new interlinking data for segment 0 is load-
ed and segment 0 is activated. Therewith, the switchover to the red curve is made.
So that the switchover to other curve areas (such as branching) can be activated as quick
as possible the switchover must be made two segments before the branching point (in
this case it is segment 1
8).
