I came across something strange that I haven’t seen in C++ before. On line 35 I dereference a iterator like this:
(*iterator)
Why do I have to use the brackets and why does *iterator not work?
I posted the code on pastebin.com for code colors:
That’s how you tell c++ what to do first.
And because iterators point to pointers It**?!
*(A)->Method(); tells the compiler to dereference A first then call Method();
More info here:

As Azarus said, it’s an order of operations issue.
http://en.cppreference.com/w/cpp/language/operator_precedence
The indirect access operator (->) has higher precedence than the dereference operator (*). Putting (*iterator) makes sure that the dereference happens first.
Okay I see. Thanks!
