void sofa::core::componentmodel::topology::TopologyModifier::notifyEndingEvent ( ) [virtual]

the end for the current sequence of topological change events.

Reimplemented in sofa::component::topology::PointSetTopologyModifier.

Definition at line 77 of file BaseTopology.cpp.

Referenced by sofa::component::collision::TopologicalChangeManager::removeItemsFromTriangleModel().

void sofa::core::componentmodel::topology::TopologyModifier::propagateStateChanges ( ) [virtual]

Called by a topology to warn the Mechanical Object component that points have been added or will be removed.

StateChangeList should contain all TopologyChange objects corresponding to vertex changes in this topology that just happened (in the case of creation) or are about to happen (in the case of destruction) since last call to propagateTopologicalChanges.

void sofa::core::componentmodel::topology::TopologyModifier::propagateTopologicalChanges ( ) [virtual]

Called by a topology to warn specific topologies linked to it that TopologyChange objects happened.

ChangeList should contain all TopologyChange objects corresponding to changes in this topology that just happened (in the case of creation) or are about to happen (in the case of destruction) since last call to propagateTopologicalChanges.
