     65@defgroup graph_adaptors Adaptor Classes for Graphs
     66@ingroup graphs
     67\brief Adaptor classes for digraphs and graphs
     68
     69This group contains several useful adaptor classes for digraphs and graphs.
     70
     71The main parts of LEMON are the different graph structures, generic
     72graph algorithms, graph concepts, which couple them, and graph
     73adaptors. While the previous notions are more or less clear, the
     74latter one needs further explanation. Graph adaptors are graph classes
     75which serve for considering graph structures in different ways.
     76
     77A short example makes this much clearer.  Suppose that we have an
     78instance \c g of a directed graph type, say ListDigraph and an algorithm
     79\code
     80template <typename Digraph>
     81int algorithm(const Digraph&);
     82\endcode
     83is needed to run on the reverse oriented graph.  It may be expensive
     84(in time or in memory usage) to copy \c g with the reversed
     85arcs.  In this case, an adaptor class is used, which (according
     86to LEMON \ref concepts::Digraph "digraph concepts") works as a digraph.
     87The adaptor uses the original digraph structure and digraph operations when
     88methods of the reversed oriented graph are called.  This means that the adaptor
     89have minor memory usage, and do not perform sophisticated algorithmic
     90actions.  The purpose of it is to give a tool for the cases when a
     91graph have to be used in a specific alteration.  If this alteration is
     92obtained by a usual construction like filtering the node or the arc set or
     93considering a new orientation, then an adaptor is worthwhile to use.
     94To come back to the reverse oriented graph, in this situation
     95\code
     96template<typename Digraph> class ReverseDigraph;
     97\endcode
     98template class can be used. The code looks as follows
     99\code
     100ListDigraph g;
     101ReverseDigraph<ListDigraph> rg(g);
     102int result = algorithm(rg);
     103\endcode
     104During running the algorithm, the original digraph \c g is untouched.
     105This techniques give rise to an elegant code, and based on stable
     106graph adaptors, complex algorithms can be implemented easily.
     107
     108In flow, circulation and matching problems, the residual
     109graph is of particular importance. Combining an adaptor implementing
     110this with shortest path algorithms or minimum mean cycle algorithms,
     111a range of weighted and cardinality optimization algorithms can be
     112obtained. For other examples, the interested user is referred to the
     113detailed documentation of particular adaptors.
     114
     115The behavior of graph adaptors can be very different. Some of them keep
     116capabilities of the original graph while in other cases this would be
     117meaningless. This means that the concepts that they meet depend
     118on the graph adaptor, and the wrapped graph.
     119For example, if an arc of a reversed digraph is deleted, this is carried
     120out by deleting the corresponding arc of the original digraph, thus the
     121adaptor modifies the original digraph.
     122However in case of a residual digraph, this operation has no sense.
     123
     124Let us stand one more example here to simplify your work.
     125ReverseDigraph has constructor
     126\code
     127ReverseDigraph(Digraph& digraph);
     128\endcode
     129This means that in a situation, when a <tt>const %ListDigraph&</tt>
     130reference to a graph is given, then it have to be instantiated with
     131<tt>Digraph=const %ListDigraph</tt>.
     132\code
     133int algorithm1(const ListDigraph& g) {
     134  ReverseDigraph<const ListDigraph> rg(g);
     135  return algorithm2(rg);
     136}
