Abstract base class for AutoContact.
To bypass the Ring/Hook mechanism and the subsequent Session::Lookup() call, the AutoSegments anchored on an AutoContact are cached in the AutoContact itself. They can be accessed through getHorizontalN()
and getVerticalN() accessors N
depending on the subtype of AutoContact.
Cached AutoSegments are updated in the AutoContact::updateTopology() function only.
The invalidation of an AutoContact invalidate all the segments that are anchored on it.
Special Case of HTee & VTee
When invalidating an HTee or VTee, two out of the three anchored segments are parallels. The aligned constraint is passed on those two. By default, when we invalidate an AutoSegment, the invalidation is applied to the whole aligned set through the AutoSegment::getAligneds() collection. So if one of the parallel is invalidated and the other not, it should only be because we are already in getAligneds()
, then we do not want to invalidate again the whole aligned set. In that case, we perform an atomic only invalidation (reset Katabatic::KbPropagate).
For the complete invalidation/revalidation mechanism see Session Algorithm.
From the previous version of Katabatic, AutoContact have been greatly stripped down (again). They are now always punctual objetcs with stricly fixed topologies:
