C++ (Cpp) to_bson_iter_t Examples

Example #1

File: view.cpp Project: jbreams/mongo-cxx-driver

view::const_iterator& view::const_iterator::operator++() {
    if (!_element) {
        return *this;
    }

    bson_iter_t i = to_bson_iter_t(_element);
    bson_iter_next(&i);

    if (!bson_iter_next(&i)) {
        _element = element{nullptr, 0, 0};
    } else {
        _element = element{i.raw, i.len, i.off};
    }

    return *this;
}

Example #2

File: view.cpp Project: acmorrow/mongo-cxx-driver

view::const_iterator& view::const_iterator::operator++() {
    if (!_element) {
        return *this;
    }

    // the bson_t pointer and length remain unchanged while iterating.
    auto raw = _element.raw();
    auto len = _element.length();

    bson_iter_t iter = to_bson_iter_t(_element);

    if (!bson_iter_next(&iter)) {
        _element = element{};
    } else {
        _element = element{raw, len, bson_iter_offset(&iter), bson_iter_key_len(&iter)};
    }

    return *this;
}
