Just a note: it should accept elemhide now

[hub, 2018/01/25 19:05:27]

It is already done. I just didn't update the review.

+{
+  intrusive_ptr<ElemHideEmulation_FilterList> result(new ElemHideEmulation_FilterList);

[sergei, 2018/01/25 16:04:01]

could you please add () to the constructor call?

[hub, 2018/01/25 19:05:27]

Done.

+  for (auto filter: mFilters)

[sergei, 2018/01/25 16:04:01]

perhaps it would be better to call it filterEntry because it's not exactly a
filter.

[hub, 2018/01/25 19:05:27]

entry like elsewhere.

Done.

+  {
+    DependentString docDomain(domain);
+    if (!filter.is_deleted() &&
+        filter.second->IsActiveOnDomain(docDomain, u""_str) &&

what do you think about having Dereferenceable iterators? E.g. *filterEntry
could be equal to filterEntry.second. Of course it's beyond the scope of the
current issue.

[hub, 2018/01/25 19:05:27]

filterEntry isn't an iterator, but the entry in the hash map. I don't think it
brings anything but confusion to do that. It is not in line with std:: either.

+        !ElemHide::GetInstance()->GetException(*filter.second, domain))
+      result->push_back(filter.second);
+  }
+
+  return result.release();
+}
