Detailed Description

Base class for topology objects.

The vtol_topology_object class is the interface base class for all topological entities. There are only access methods in this class. vtol_topology_object inherits from vtol_spatial_object, which is the base class for all topology and geometry.

The topology class hierarchy:

                               vtol_topology_object
                                     |
               |        |       |       |       |       |        |
           vertex  zero_chain  edge  one_chain  face  two_chain  block
               |                |               |
          vertex_2d           edge_2d          face_2d

(Actually, one_chain and two_chain share a common parent class vtol_chain, but that's just a matter of convenience; conceptually, the scheme is this.)

   Incidence of:
         (vsol_point)      (vsol_curve)     (vsol_surface)    (vsol_volume)
   Directed
   Sequence of:       vertex           edge             face

The vertex, edge and face entities account for incidence between points, curves and surfaces, respectively. For example, two vtol_edge(s) are incident at exactly one vtol_vertex. That is, an edge does not intersect itself or another edge, except possibly at a vertex. The chain entities are directed sequences which define composite structures. Each element of the chain has a sign associated with with it denoting the "direction" of use in a boundary traversal. For example, a closed vtol_one_chain (a 1-cycle) forms the boundary of a surface region. Two adjacent surface regions (vtol_face(s)) use an edge in the opposite sense in their bounding 1-chains.

The data member "inferiors_" stores a list of all topology objects of the type "below" the current one, which form the boundary of this one. All these objects should have the current object listed in their "superiors_" list. It is the responsibility of the superior to break the link with its inferior, not vice versa, hence conceptually the "superiors_" entries are under control of the referred superior object. Otherwise said, an object cannot live without its inferiors (and will disappear when its inferiors disappear), while an object can live without its superiors (and is just notified of their appearance and disappearance by the entries listed in its superiors_ list).

As a consequence, the "inferior" does not obtain a new time stamp when its superiors change (hence its "superiors_" list is mutable). This also explains why the "superiors_" list consists of ordinary pointers, not smart pointers: the refcount toggling is done from superior to inferior (which requires its inferiors to be kept alive), not from inferior to superior (which need not bother about its superiors' existence).

    Modifications
     ported to vxl by Luis E. Galup
     JLM November 2002 - added a local bounding box method
     dec.2002 -Peter Vanroose- added chain_list (typedef) and cast_to_chain()
     dec.2002 -Peter Vanroose- link_inferior() now takes smart pointer argument
     sep.2004 -Peter Vanroose- made methods returning the inf_sup cache "const"
