CannotImplementInterfaceInBlueprint

This interface cannot be implemented by a Blueprint (e.g., it has only non-exposed C++ member methods).

Any interfaces that define a function that isn't a BlueprintImplementableEvent or BlueprintNativeEvent must be declared as CannotImplementInterfaceInBlueprint.

Usage

UINTERFACE(meta=(CannotImplementInterfaceInBlueprint))
class ClassName : UInterface
{
    GENERATED_UINTERFACE_BODY()
};
