AngelScript: execute function returning parameters

I have an array of strings representing objects.
I want to construct the objects without too many ifs.

Array<String> stuff = {
   "bh_node1",
   "bh_node2",
...
}

Array<TreeElement@> items;

....
for (int i = 0; i < stuff.length; i++) {
    if (stuff[i] == "bh_node1")
        items.Push(ConstructBhNode1());
    else if (stuff[i] == "bh_node2")
        items.Push(ConstructBhNode2());
...
}

I’m not really happy with all this long lines with ifs and hardcoding data in code.
Is there some way to produce lists, line in C or C++ where I could just run respective pointer?
Otherwise it looks very annoying and hard to maintain…

You can use funcdefs and creators functions, like this:

interface SomeIface {
	void printName();
};

class IfaceImpl1 : SomeIface {
	void printName() {
		Print("Impl1");
	}
};

class IfaceImpl2 : SomeIface {
	void printName() {
		Print("Impl2");
	}
};

funcdef SomeIface@ IfaceCreator();

SomeIface@ creator1() {
	return IfaceImpl1();
}

SomeIface@ creator2() {
	return IfaceImpl2();
}

Dictionary creators = {{"impl1", creator1},{"impl2", creator2}};

SomeIface@ createByName(const String& name) {
	if (creators.Exists(name)) {
		IfaceCreator@ c = cast<IfaceCreator>(creators[name]);
		return c();
	}
	return null;
}

void test() {
	SomeIface@ iface = createByName("impl1");
	iface.printName();
	@iface = createByName("impl2");
	iface.printName();
}

Or if your objects links to nodes, you can use ScriptObject - it is created by name.

Thanks a lot!
The solution is nice!
