7 | It is quite easy to write your own readmap for the edges or nodes of a graph. |
---|
8 | |
---|
9 | You can find some example below. |
---|
10 | |
---|
11 | This simple map assigns \f$\pi\f$ to each edge. |
---|
12 | |
---|
13 | \code |
---|
14 | class MyMap |
---|
15 | { |
---|
16 | double get(Graph::EdgeIt e) { return M_PI;} |
---|
17 | }; |
---|
18 | \endcode |
---|
19 | |
---|
20 | Or if we accept the new map style, it will look like this: |
---|
21 | |
---|
22 | \code |
---|
23 | class MyMap |
---|
24 | { |
---|
25 | double operator[](Graph::EdgeIt e) { return 1;} |
---|
26 | }; |
---|
27 | \endcode |
---|
28 | |
---|
29 | |
---|
30 | A more complex example |
---|
31 | |
---|
32 | \code |
---|
33 | class MyLengthMap |
---|
34 | { |
---|
35 | const Graph::EdgeMap &ol; |
---|
36 | const Graph::NodeMap &pot; |
---|
37 | |
---|
38 | double get(Graph::EdgeIt e) const { return ol.get(e)-pot.get(v)-pot.get(u);} |
---|
39 | |
---|
40 | MyComplexMap(const Graph::EdgeMap &o,const Graph::NodeMap &p) : |
---|
41 | ol(o), pot(p); |
---|
42 | }; |
---|
43 | \endcode |
---|
44 | |
---|
