Detailed Description

iterator for ZFFramework

zfiter is an abstract iterator holder, which simply stores an void * pointer for implementations to achieve iterator logic

typically, you may use iterators like this:

for(zfiter it = someIterable.iter(); it; ++it) {
    const SomeType &value = someIterable.iterValue(it);
}

for key-value container, access by iterator should return value, and should supply key-value version of iterator access:

for(zfiter it = keyValueIterable.iterFind(key); it; ++it) {
    // access key and value
    KeyType key = keyValueIterable.iterKey(it);
    ValueType value = keyValueIterable.iterValue(it);
}

for implementations, you should construct a zfiter with proper zfiter::Impl
