"Conoscenza Silente"
I would like to fasten up the whole process; let's say that I would like to avoid the creation/destruction of the class each time using object already allocated in memory that are deleted only at the exit of the application. Is this a good way in your opinion ?
You might want to read the Performance section: http://www.boost.org/libs/statechart/doc/performance.html Bottom line: Unless you're writing a parser with Boost.Statechart, state construction & destruction usually doesn't constitute a perf bottleneck in an application. For parsing there are much more suitable tools (Spirit, Regex, etc.). HTH, -- Andreas Huber When replying by private email, please remove the words spam and trap from the address shown in the header.
