[Boost-users] [BGL] Is it possible to control algorithm's behavior by visitor?

In some complex application, I need to control algorithm's behavior according to edge's property. It seems all visitor are used to "visit" the predefined place in a algorithm but it can not "control". All functions in visitor has void return type, so it can't give algorithm anything. Why there is no STL-like functor which can control algorithm's behavior? -- View this message in context: http://www.nabble.com/-BGL--Is-it-possible-to-control-algorithm%27s-behavior...
