void
|
v.on_anihiliation_event_processed ( Vertex_ _handle const node0, Vertex_ _handle const node1)
|
| |
Called after an anhiliation event for nodes node0 and node1 has been processed.
A new skeleton edge between these nodes has been added.

void
|
|
v.on_edge_event_processed ( |
Vertex_ _handle const seed0,
Vertex_ _handle const seed1,
Vertex_ _handle const newnode) |
|
| |
Called after an edge for nodes seed0 and seed1 has been processed.
Skeleton vertex newnode and edges from node0 to newnode and node1 to newnode
has been added.

|
v.on_split_event_processed ( |
Vertex_ _handle const seed,
Vertex_ _handle const newnode0,
Vertex_ _handle const newnode1) |
|
| |
Called after a split event for node seed has been processed.
Skeleton vertices newnode0 and newnode1 have been added.
An skeleton edge from seed to newnode0 has been added.
In the final skeleton, newnode1 is removed and only newnode0 remains.

|
|
void
|
v.on_cleanup_finished ()

|
|
void
|
v.on_algorithm_finished ( bool finished_ok)
|
| |
