|
virtual void | on_started (ComplexType &complex) |
| | Called before the edge contraction process starts.
|
| |
|
virtual void | on_stop_condition_reached () |
| | Called when the algorithm stops.
|
| |
|
virtual void | on_collected (const Profile &profile, boost::optional< FT > cost) |
| | Called during the collecting phase (when a cost is assigned to the edges), for each edge collected.
|
| |
|
virtual void | on_selected (const Profile &profile, boost::optional< FT > cost, int initial_count, int current_count) |
| | Called during the processing phase (when edges are contracted), for each edge that is selected.
|
| |
|
virtual void | on_contracting (const Profile &profile, boost::optional< Point > placement) |
| | Called when an edge is about to be contracted and replaced by a vertex whose position is *placement.
|
| |
|
virtual void | on_contracted (const Profile &profile, boost::optional< Point > placement) |
| | Called when after an edge has been contracted onto a new point placement. A possibility would to remove popable blockers at this point for instance.
|
| |
|
virtual void | on_non_valid (const Profile &profile) |
| | Called for each selected edge which cannot be contracted because the ValidContractionPredicate is false.
