Re: [Boost-users] Boost lambda: iter_swap and treating lambda as iterator.

4 May 2006


      So is there any way to treat lambda like an iterator so i can compare them
to another iterator value or perform iter_swap on them thanks?

K the question is simple. How do i do iterator swap with lambda.
lets say i have vector of U.
vector<U> vecU;
typedef vector<U>::iterator iter;
iter beg(vecU.begin());
for_each(vec.begin(), vec.end(),
(
    if_(_1 == *beg)
    [
        // swap the iterator between the current one and begin.
    ]
)
);
