Hi all,
I am storing a set of functors to be invoked in a vector, like this:
std::vector< boost::function<void> > functors;
At a later time, I would like to invoke each of the functors in the
vector. I am trying to do this using Boost.Lambda, to start learning
about the Lambda library, but I can't figure out what to write.
if I write:
std::for_each(functors.begin(), functors.end(), _1);
None of the functions are invoked.
if I try:
for_each(funtors.begin(), functors.end(), _1());
I get compile errors. I suspect this is because the lamda expression is
being executed immediately instead of getting passed in to for_each.
Everything works fine when I use a separate Invoker function in the
usual fashion, like this:
void Invoker( boost::function<void> functor) {
functor();
}
std::for_each(funtors.begin(), functors.end(), Invoker);
How can I get the lambda library to invoke each function in the
vector? More generally, if the functions were function
