Search vector of boost::tuple

So I have this vector:

  vector<boost::tuple<ppa::Node*, ppa::Node*, ppa::Node*, bool> > wait;

And I want to search if for the ones that have true in them, how can I do that, that's it.

Any suggestion I have looked into boost::phoenix but not really sure how it works, any ideas.

Thanks.

Since you are just starting off, here is some example code (I don't what compiler you are using, but you could use auto, range-based for etc. if you have C++11 support):

typedef vector<boost::tuple<ppa::Node*, ppa::Node*, ppa::Node*, bool> >::iterator vec_iter;
for (vec_iter i = wait.begin(); i != wait.end(); ++i)
{
    if (boost::get<3>(*i) == true)
    {
       // This tuple has true in it, so do something
    }
}

C++11 version:

for (auto& i : wait)
{
    if (boost::get<3>(i) == true)
    {
        // Do stuff
    }
}

Something like this std::find_if(wait.begin(),wait.end(),istruetuple)...
