  // The simple graph's can be refered as two containers, one node container
39
  // and one edge container. But they are not standard containers they
40
  // does not store values directly they are just key continars for more
41

  // The node and edge sets of the graphs can be changed as we add or erase
44 44
  // nodes and edges in the graph. LEMON would like to handle easily
45 45
  // that the node and edge maps should contain values for all nodes or
46 46
  // edges. If we want to check on every indicing if the map contains
47 47
  // the current indicing key that cause a drawback in the performance

  // in the library. We use another solution we notify all maps about

  // in the library. We use another solution: we notify all maps about
49 49
  // an alteration in the graph, which cause only drawback on the
50 50
  // alteration of the graph.
51 51

52
  // This class provides an interface to the container. The \e first() and \e
53
  // next() member functions make possible to iterate on the keys of the
54
  // container. The \e id() function returns an integer id for each key.
55
  // The \e maxId() function gives back an upper bound of the ids.

56
  // The maxId() function gives back an upper bound of the ids.
56 57
  //
57 58
  // For the proper functonality of this class, we should notify it
58
  // about each alteration in the container. The alterations have four type
59
  // as \e add(), \e erase(), \e build() and \e clear(). The \e add() and
60
  // \e erase() signals that only one or few items added or erased to or
61
  // from the graph. If all items are erased from the graph or from an empty
62
  // graph a new graph is builded then it can be signaled with the
59
  // about each alteration in the container. The alterations have four type:
60
  // add(), erase(), build() and clear(). The add() and
61
  // erase() signal that only one or few items added or erased to or
62
  // from the graph. If all items are erased from the graph or if a new graph
63
  // is built from an empty graph, then it can be signaled with the
63 64
  // clear() and build() members. Important rule that if we erase items
64
  // from graph we should first signal the alteration and after that erase
65
  // from graphs we should first signal the alteration and after that erase
65 66
  // them from the container, on the other way on item addition we should
66 67
  // first extend the container and just after that signal the alteration.
67 68
  //
68 69
  // The alteration can be observed with a class inherited from the
69
  // \e ObserverBase nested class. The signals can be handled with
70
  // ObserverBase nested class. The signals can be handled with
70 71
  // overriding the virtual functions defined in the base class.  The
71 72
  // observer base can be attached to the notifier with the
72
  // \e attach() member and can be detached with detach() function. The
73
  // attach() member and can be detached with detach() function. The
73 74
  // alteration handlers should not call any function which signals
74 75
  // an other alteration in the same notifier and should not
75 76
  // detach any observer from the notifier.
76 77
  //
77
  // Alteration observers try to be exception safe. If an \e add() or
78
  // a \e clear() function throws an exception then the remaining
78
  // Alteration observers try to be exception safe. If an add() or
79
  // a clear() function throws an exception then the remaining
79 80
  // observeres will not be notified and the fulfilled additions will
80
  // be rolled back by calling the \e erase() or \e clear()
81
  // functions. Thence the \e erase() and \e clear() should not throw
82
  // exception. Actullay, it can be throw only \ref ImmediateDetach
