//\brief Observer notifier for graph alteration observers.

namespace lemon {

  // \ingroup graphbits

  //

  // \brief Notifier class to notify observes about alterations in

  // a container.

  //

  // The simple graphs can be refered as two containers: a node container

  // and an edge container. But they do not store values directly, they

  // are just key continars for more value containers, which are the

  // node and edge maps.

  //

  // The node and edge sets of the graphs can be changed as we add or erase

  // nodes and edges in the graph. LEMON would like to handle easily

  // that the node and edge maps should contain values for all nodes or

  // edges. If we want to check on every indicing if the map contains

  // the current indicing key that cause a drawback in the performance

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

  // an alteration in the graph, which cause only drawback on the

  // alteration of the graph.

  //

  // This class provides an interface to a node or edge container.

  // The first() and next() member functions make possible

  // to iterate on the keys of the container.

  // The id() function returns an integer id for each key.

  // The maxId() function gives back an upper bound of the ids.

  //

  // For the proper functonality of this class, we should notify it

  // about each alteration in the container. The alterations have four type:

  // add(), erase(), build() and clear(). The add() and

  // erase() signal that only one or few items added or erased to or

  // from the graph. If all items are erased from the graph or if a new graph

  // is built from an empty graph, then it can be signaled with the

  // clear() and build() members. Important rule that if we erase items

  // from graphs we should first signal the alteration and after that erase

  // them from the container, on the other way on item addition we should

  // first extend the container and just after that signal the alteration.

  //

  // The alteration can be observed with a class inherited from the

  // ObserverBase nested class. The signals can be handled with

  // overriding the virtual functions defined in the base class.  The

  // observer base can be attached to the notifier with the

  // attach() member and can be detached with detach() function. The

  // alteration handlers should not call any function which signals

  // an other alteration in the same notifier and should not

  // detach any observer from the notifier.

  //

  // Alteration observers try to be exception safe. If an add() or

  // a clear() function throws an exception then the remaining

  // observeres will not be notified and the fulfilled additions will

  // be rolled back by calling the erase() or clear() functions.

  // Hence erase() and clear() should not throw exception.

  // Actullay, they can throw only \ref ImmediateDetach exception,

  // which detach the observer from the notifier.

  //

  // There are some cases, when the alteration observing is not completly

  // reliable. If we want to carry out the node degree in the graph

  // as in the \ref InDegMap and we use the reverseArc(), then it cause

  // unreliable functionality. Because the alteration observing signals

  // only erasing and adding but not the reversing, it will stores bad

  // degrees. Apart form that the subgraph adaptors cannot even signal

  // the alterations because just a setting in the filter map can modify

  // the graph and this cannot be watched in any way.

  //

  // \param _Container The container which is observed.

  // \param _Item The item type which is obserbved.
