"indexitor" container now handles skips correctly.

[Mr Flibble]

Hi!

My indexitor container now handles skips correctly:

#include <string>
#include <iostream>
#include <neolib/indexitor.hpp>

int main()
{
neolib::indexitor<std::string, int> idx;
typedef neolib::indexitor<std::string, int>::skip_type skip;

idx.push_back(std::make_pair("xyzzy", 5), skip{ 2, 2 });
idx.push_back(std::make_pair("neo", 5), skip{ 5, 0 });
idx.push_back(std::make_pair("kitteh", 5), skip{ 3, 1 });

for (auto i = idx.begin(); i != idx.end(); ++i)
std::cout << "Foreign index of " << i->first << " is " <<
idx.foreign_index(i) << std::endl;

std::cout << "All foreign indexes:-" << std::endl;
for (int i = 0; i < idx.foreign_index(idx.end()); ++i)
{
auto v = idx.find_by_foreign_index(i);
if (v.first != idx.end())
std::cout << i << ": " << v.first->first << std::endl;
else
std::cout << i << ": <null>" << std::endl;
}

return 0;
}


outputs:

Foreign index of xyzzy is 2
Foreign index of neo is 14
Foreign index of kitteh is 22
All foreign indexes:-
0: <null>
1: <null>
2: xyzzy
3: xyzzy
4: xyzzy
5: xyzzy
6: xyzzy
7: <null>
8: <null>
9: <null>
10: <null>
11: <null>
12: <null>
13: <null>
14: neo
15: neo
16: neo
17: neo
18: neo
19: <null>
20: <null>
21: <null>
22: kitteh
23: kitteh
24: kitteh
25: kitteh
26: kitteh
27: <null>
