void sofa::component::topology::PointSetTopologyModifier::notifyEndingEvent ( ) [virtual]

void sofa::component::topology::PointSetTopologyModifier::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.

virtual void sofa::component::topology::PointSetTopologyModifier::removeItems ( sofa::helper::vector< unsigned int > & ) [inline, virtual]

Generic method to remove a list of items.

Reimplemented from sofa::core::componentmodel::topology::TopologyModifier.

Reimplemented in sofa::component::topology::EdgeSetTopologyModifier, sofa::component::topology::HexahedronSetTopologyModifier, sofa::component::topology::ManifoldEdgeSetTopologyModifier, sofa::component::topology::QuadSetTopologyModifier, sofa::component::topology::TetrahedronSetTopologyModifier, and sofa::component::topology::TriangleSetTopologyModifier.

void sofa::component::topology::PointSetTopologyModifier::removePointsProcess	(	const sofa::helper::vector< unsigned int > &	indices,
		const bool	removeDOF = `true`
	)			`[virtual]`

Remove a subset of points.

Elements corresponding to these points are removed from the mechanical object's state vectors.

Important : some structures might need to be warned BEFORE the points are actually deleted, so always use method removePointsWarning before calling removePointsProcess.

See also:: removePointsWarning

Parameters:

	indices	is not const because it is actually sorted from the highest index to the lowest one.
	removeDOF	if true the points are actually deleted from the mechanical object's state vectors
