OOP at home:

In case anyone is wondering:
The artist is Princess Hinghoi.
Looks like some circular inheritance, that's going to cause some issues down stream.
Trust the vibe, bro, if it was wrong it wouldn't vibe like that bro
sometimes i wonder what dignity means to certain artists
My guess is that money overwrites dignity in some cases.
Implying that's not their kink in the first place
Incest?
Sure seems like it.
I'm taking the blonde with the succubus tattoo
Everyone that knows what that is is a pervert
Entity Component System all the things!
I might write an XML ECS parser, as a joke. Practical? No! Probably even slower than the XML DOM? Yes! Funny? Yes!
I'll say this now.
Inheritance is the most misused capability of OOP which programmers think makes their code look smart, but most of the time just makes a giant fucking mess.
I've moved away from Classes in general unless it truly makes code more streamlined. The main language I was taught in highschool was Java and it's just so liberating not needing to turn everything into an object.
But recently I've used a Class specifically for Inheritance. I'm making an extension to Pytorch and almost everything in Pytorch uses Tensors as a medium. I made a new kind of tensor that inherits the Tensor class to add specific restrictions on how it behaves. Because of this, this new tensor object can be used with any of the preexisting pytorch functions while also validating the results, reverting to a Tensor if it becomes invalid.
Even in this situation though, all my programming logic rests in it's own static functions, and the class contains functions that call the static version. The only actual logic the inherited object handles is validating the data.
Because of this, I feel like inheritance is most useful when you're inheriting someone else's code to make it compatible with their library. I don't think I'll ever inherit my own objects because that's how you end up with Java.
Its the best/worst thing about OOP no matter what language.
We had a rule at work that if you are 3 levels or more down an inheritance tree, then you are too far. The cognitive load is just too much, plus everything stops making sense.
One level can be great (MVC all have great conventions, MCP as well). Two can be pushing it (Strategy pattern when you have physical devices and cant be connected all the time, Certain kinds of business logic that repeat hundreds of times, etc...) But even there you are kinda pushing it.
I need code that I can look at a month from now and know WTF is happening. And sometimes its better to have less DRY and more comprehension. Or maybe im just a forever mediocre dev and dont see the "light". I dunno.
composition can help with all of that. factories, strategies, injections are all composition patterns that work fine.
business logic that repeats? extract it to it's own thing (class, function, etc) and pass it as a param to the supposed childs.
mvc? controllers don't need to extend anything, just have them accept the framework through the constructor and request and response as args. views? same. models? perhaps only if doing an active record, but a repo pattern with plain objects is a good pattern too.
I never seen a clean inheritance implementation for a decently sized problem. it mostly works for tiny ones.
When I first started using Go I bemoaned the lack of true inheritance and classes. Now I love it.
I thought it didn't have classes in name only, isn't a struct with methods basically a class?
Depends on what you mean by “basically a class”. If you mean inheritance, overriding, and more generally class/inheritance based polymorphism, no, it does not. Those require dynamic dispatch, which Go does not have (for concrete types, which is what we’re talking about here).
a class can be inherited from, a struct can not.
This is exactly how I feel too. A little bit of repetition is totally worth it, versus having inappropriate coupling, or code that jumps in and out of parent/child classes everywhere so you can hardly keep it in your head what's going on.
I freely accept that I AM a mediocre dev, but if that lends me to prefer code that is comprehensible and maintainable then I think being mediocre is doing my team a favour, honestly.

Hold on, I’m in the middle of drawing an inheritance graph so I know how Dog is related to AircraftCarrier.
public interface ICanTravelThroughTheAir
{
}
public class Flea : ICanTravelThroughTheAir
{
}
public class AircraftCarrier
{
private readonly List<ICanTravelThroughTheAir> _aircraft = new();
public void AddAircraft(ICanTravelThroughTheAir flyingThing)
{
_aircraft.Add(flyingThing);
}
}
public class Dog : AircraftCarrier
{
public void Woof()
{
Console.WriteLine("Bitch I'm an aircraft carrier!");
}
}
public static class Program
{
public int Main(string[] args)
{
var dog = new Dog();
for (var i = 0; i < 10000; i++)
{
dog.AddAircraft(new Flea());
}
dog.Woof();
}
}
Now someone needs to make it an entity component system!
Attempt 1:
public struct Entity {
bool isDog : 1;
bool isAircraftCarrier : 1;
bool isFlea : 1;
bool canFlyInAir : 1;
ubyte opt_numOfAircrafts : 4;
int entityID;
int opt_parentID;
static Entity createDog(int entityID) {
Entity result;
result.isDog = true;
result.entityID = entityID;
return result;
}
static Entity createFlea(int entityID) {
Entity result;
result.isFlea = true;
result.canFlyInAir = true;
result.entityID = entityID;
return result;
}
void addAirCraft(ref Entity aircraft) {
if (aircraft.canFlyInAir && this.isAircraftCarrier) {
aircraft.opt_parentID = this.entityID;
this.opt_numOfAircrafts++;
}
}
void woof() {
if (isDog) {
if (isAircraftCarrier) writeln("I'm a motherfucking aircraft carrier");
else writeln("Woof!");
}
}
}
void main() {
Entity dog = Entity.createDog(1);
Entity flea = Entity.createFlea(2);
dog.woof();
dog.isAircraftCarrier = true;
dog.addAirCraft(flea);
dog.woof();
}
You forgot the component part.

The venerable master Qc Na was walking with his student, Anton. Hoping to prompt the master into a discussion, Anton said "Master, I have heard that objects are a very good thing - is this true?" Qc Na looked pityingly at his student and replied, "Foolish pupil - objects are merely a poor man's closures."
Chastised, Anton took his leave from his master and returned to his cell, intent on studying closures. He carefully read the entire "Lambda: The Ultimate..." series of papers and its cousins, and implemented a small Scheme interpreter with a closure-based object system. He learned much, and looked forward to informing his master of his progress.
On his next walk with Qc Na, Anton attempted to impress his master by saying "Master, I have diligently studied the matter, and now understand that objects are truly a poor man's closures." Qc Na responded by hitting Anton with his stick, saying "When will you learn? Closures are a poor man's object." At that moment, Anton became enlightened.

In over ten years of professional programming, I have never used inheritance without regretting it.
This applies to firewall rules too
Do you include "traits" and "interfaces" under the title "inheritance"?
No because those are different things.
When it's the right tool, it's incredibly useful. When it's the wrong tool, and it often is, it racks up tech debt at an incredible rate.

Examples of inheritance hierarchies are always totally useless shit like this - what if a cow is an animal; What if a cow is a mammal, all mammals are animals and all mammals have a lactate() method?
Yeah... Wheres the AbstactAnimalFactoryManager?
I always knew Mondrian was painting cow production machines.
Because any real life use that might come to mind would probably be related to some NDA protected database in a company.
And it is otherwise hard to think of anything at the spot, so just go with what the first example on the web-search came up with.
Composition over inheritance every day, all day
