Kinetic::DelaunayTriangulationVisitor_3 Concept Reference
Concepts

## Definition

This concept is for proxy objects which get notified when a kinetic Delaunay triangulation changes.

Has Models:

  `CGAL::Kinetic::Delaunay_triangulation_visitor_base_3`

  `CGAL::Kinetic::Delaunay_triangulation_event_log_visitor_3`

## Operations

void | pre_remove_vertex (Vertex_handle)
| The vertex is about to be deleted.
void | post_remove_vertex (Point_key, Cell_handle)
| The vertex was just removed.
void | pre_insert_vertex (Point_key, Cell_handle)
| The vertex is about to be inserted into the cell (although the `Cell_handle` might be `NULL`).
void | post_insert_vertex (Vertex_handle)
| The vertex was just inserted.
void | change_vertex (Vertex_handle)
| The trajectory of the point at the vertex changed.
void | create_cell (Cell_handle)
| The cell was just created and initialized.
void | destroy_cell (Cell_handle)
| The cell is about to be removed.
void | pre_edge_flip (Edge)
| The edge is about to be flipped.
void | post_edge_flip (Facet)
| The facet was just created with a flip.
void | pre_facet_flip (Facet)
| The facet is about to be flipped.
void | post_facet_flip (Edge)
| The edge was just created with a flip.
