Unreal Engine 4 Scripting with C++ Cookbook

Specifying a UCLASS as the type of a UPROPERTY

So, you've constructed some custom UCLASS intended for use inside UE4. But how do you instantiate them? Objects in UE4 are reference-counted and memory-managed, so you should not allocate them directly using the C++ keyword new. Instead, you'll have to use a function called ConstructObject to instantiate your UObject derivative. ConstructObject doesn't just take the C++ class of the object you are creating, it also requires a Blueprint class derivative of the C++ class (a UClass* reference). A UClass* reference is just a pointer to a Blueprint.

How do we instantiate an instance of a particular Blueprint from C++ code? C++ code does not, and should not, know concrete UCLASS names, since these names ...
