A derived function with a different signature than a base class function will result in the base class function of the same name being hidden. The parameter list and return type for the member function in the derived class must match those of the member function in the base class, otherwise the function in the derived class will hide the function in the base class and no polymorphic behaviour will occur. This patch addresses these warnings by ensuring a unique function name to avoid (unintentionally) hiding any functions.
