In the Vehicle collection I have two different types of documents - Suv and Truck. My models look like this: public abstract class BaseCar { publ ...
I am trying to extend std::map's std::pair entries with some extra functionality and want to cast such pairs to a child class of pair. Note that this ...
could someone explain what is meant when they say that overloading occurs at compile time whereas overriding occurs at runtime? My understanding is ov ...
I can not seem to make head or tails of this Raku error message I found while exploring grammars... So an Array is not an Array?! How does that ...
I am trying to get the size of a derived class, but I can't... The output is always 8! ...
I learned the concept of polymorphism and I am trying to use the concept in order to create a map called "pipeline" that takes a vector of inputs (the ...
I have two classes, Base and Derived: The function that creates the objects in run time uses the following method: When this runs, the output ...
I'm writing a piece of code in which I need to call an overridden method of a parent class. This is easy to do in C++: However, I need to do this i ...
I'm looking to make class A a generic UI Inputbox, that holds a member B that gets a constructor argument with variable type. Class A should then be a ...
I wonder if there is any benefit of using CRTP over virtual function polymorphism if I never invoke the function from the base class (i.e., virtual di ...
how can I implement polymorphism using an abstract class for handling product saving, deleting, and showing for three different product types? there a ...
I was hoping to define an interface hierarchy, where the base interface declares a function, and each extension's version of that function receives it ...
I have two methods that perform the same task: one receiving an array parameter and the a List parameter, both of type string. Is there a way to repla ...
I want a method to do a consistent thing in base class while derived classes can have it do something different (hence it being virtual), while requir ...
I want to implement a simple one-to-many data structure in Haskell. Each key of type k associated with set of elements of type v. m here is a type ...
Imagine an array_slice method which returns a part of an array. Imagine also that your program is using multiple memory allocation strategies, like Bo ...
I am relatively new to object inheritance, I am aware of rule of 0/3/5, but I have always avoided deriving classes and mainly wrote codes applying rul ...
I am trying to overload a virtual function, like this: #include<iostream> #include<string> using std::cout; using std::endl; using std::s ...
assuming I have a base class called AnimalTypes and 3 derived classes, all 4 containing only variables. What I want to do is to create a List or an Ob ...
