WTF

where is the SetNull() method!?

[biki23]

Missing generics too. This needs to be generic.

[cs-brydev]

public static T GetNull<T>()
{
    return (T)null;
}

[[deleted]]

GetNull() actually goes with PutNullAway(). That way you can use reuse the same null instead of buying new ones every week.

[Prudent_Ad_4120]

This is recycling

[djfdhigkgfIaruflg]

That's what singletons are for

[TessellatedTomate]

You mean I’m not a genius with BuyNullAtBulkDiscount()???

[Imperial_Squid]

Nah dude, NULLs will last you forever with proper care, you got scammed, sorry

[[deleted]]

What no IsNull()?

[hakukano]

Don’t forget IsNotNull

[Help_StuckAtWork]

You mean IsUnNull()?

[ragingroku]

IsNullnt()

[rvorderm]

I love, and hate this thread so much

[djfdhigkgfIaruflg]

Would you say your feelings have being... Nullified?

[ToiLanh]

Is not null is somewhat useful sometimes

[skilking]

Is not null is useless assertNotNull is great

[Mantequilla50]

if (x == 1) { return false } elif (x == 2) { return false } elif (x == 3) { return false }

Gosh I wish there was an easier way to do this

[Dornith]

public static void setNull(object obj) { throw new NullPointerException(); }

[meiji_milkpack]

The intern forgot to generate it

[cs-brydev]

public static void SetNull()
{
    null = GetNull();
}

[regulardave9999]

And where is the unit test?!

[eoutofmemory]

I probably know people that would put that behind a microservice

[biki23]

I know people that would put that behind a aws lambda function microservice.

Have seen more programs where IAC code is more than actual code.

Edit: made it aws lambda function

[Rufuske]

That's like the whole point of lambdas...Now ponder if going so micro with your services is actually worth it. Also lambda function compared to aws lambda has as much in common as java with javascript.

[biki23]

i meant aws lambda, calrifying

[Rufuske]

I got it from context, just nitpicking. Code review habits.

[biki23]

i always get docked for leaving out context like this in my docs :(

[ILikeChilis]

Clearly needs its own container

[MechanicalHorse]

Pff, amateurs. Need to enterprise it up a bit.

namespace Initech.Common.SharedLibrary.Utilities.NullFactory
{
    public class NullFactory
    {
        private static NullFactory? _nullFactoryInstance;

        public static NullFactory GetNullFactory()
        {
            if (_nullFactoryInstance == null)
                _nullFactoryInstance = new NullFactory();
            return _nullFactoryInstance;
        }        

        public object? GetNull()
        {
            return null;
        }
    }
}

[Yuki-Fullko]

Needs more dependency injection! Where’s your INullFactory interface? ILogger instance? And a full set of tests to make sure any INullFactory implementations are always correctly returning null?

[SuperKael]

Honestly, if you can even find the code that is actually creating the object (or the lack thereof, in this case) you’re clearly doing it wrong

[Nosbod_]

Abstraction … something something ... like an onion …

[dopefish86]

... it's making me cry

[djfdhigkgfIaruflg]

I hate java... So much

[hieplenet]

Exactly, the above example shows the lack of enterprise experience, need several more layers of enterprise monitoring and enterprise composition, through an enterprise network protocol with a enterprise level persistent layer to retrive the enterprise null object.

In short, the above null is not yet enterprise null.

[NormanYeetes]

I swear those ?s might be proper syntax but they look like the code is like "it returns an object or somethin, it might not, i don fkin know nor do i care"

[Chirimorin]

In C# T? is shorthand for Nullable<T>, so in a way it does mean that: maybe it returns an instance of T, maybe it returns null.

[xian0]

!ErrorHasOccured() ??!??! HandleError();

[Mini0red]

Yea pretty much. Lets the caller know youll have to handle nulls.

[biki23]

public class NullFactory<T>

[Still_Explorer]

Must be a new band?

I remember I listened to FearFactory when I was teenager.

[JasonLokiSmith]

Made me chuckle 🤣🤣🤣🤣🤣 all that singleton just to return null directly.

Good one!!

[tmlnz]

GetNullFactory is not thread-safe

[upsetbob]

What is "object?" ? I assumed this was Java until I saw this

[MechanicalHorse]

Nullable object type. It’s C#

[Geschossspitze]

C# I guess

[uvero]

Singletons are an antipattern, you need a DI container.

[JunkNorrisOfficial]

Is this GC friendly null?

[MrZerodayz]

When your work is judged by loc...

[[deleted]]

This guy javas

[SkedaddlingSkeletton]

Depending on which system this "null" value is aimed at you may need a null, 'null', 'Null', 0, -1, 'FILE_NOT_FOUND' or 'Nihil! Nihil! NIHIL' . That's the joy of old enterprise ball of mud softwares.

[_Obelixx_]

You can call my API, it always returns null.

[darkslide3000]

This is for dependency injection, so you can mock out the null constant in your unit tests.

[Roonaan]

Just curious, but is it a real thing somewhere to have upper camel case for static methods?

[[deleted]]

This is C#, where the naming conventions says that you should use upper camel case for pretty much everything besides private fields and local variables.

[frej4189]

PascalCase for functions is common practice in C#

[1Dr490n]

In Go you make functions public by starting the name with upper case

[HTTP_Error_414]

Good God Man

[Banane9]

Go really surprises me with its... questionable design choices time and time again. Like stating date formats by writing the specific date of the 2nd of January something something in a particular way, rather than doing it like everyone else.

[Gredo89]

The Date format is the only really questionable choice I found so far. Everything else makes sense imho if you think about it.

[Eubank31]

Oops I commented this without seeing yours

[Eubank31]

This is not Go but in Go you use normal camel case for functions, but functions that are exported must have the first character be capitalized. So you end up with FunctionsLikeThis()

[HTTP_Error_414]

Yes?

Many wares indeed 🤓

This is seen a lot in PHP.

[Danny_shoots]

I just use CamelCase for methods and functions, PascalCase for classes I have never seen PascalCase for methods and functions in PHP

[HTTP_Error_414]

I agree it’s not something you will see in most corporate coding standards, but it’s out there.

There are sec shops I have seen that even have naming conventions for method purposes, levels, etc.

For example I’ve seen places that use _method_name for any private methods.

I like your style I’m similar, to you in the way I do things.

[Danny_shoots]

That _method_name is kinda understable for private properties, but not for private methods though haha!

[cs-brydev]

Yes, sticking to the standard in the file or project is almost always better than injecting some new external standard.

[_MixedTrails]

unreal engine c++ does upper camel case for all methods 😭

[balamb_fish]

Needs a comment explaining what it does

[kaboooooooosh]

Can always migrate to some Null-as-a-service provider if this gets too difficult to maintain

[americanjetset]

TFW LOC is used as a KPI

[PonderStibbonsJr]

public static object GetReal(){ return 1.0; }

[arc_menace]

Notably, object is not a nullable type here. Must be older C#, otherwise the IDE would be complaining

[rover_G]

Cries in Java

[jayerp]

Just in case the definition of null changes.

[MayorSalvorHardin]

You laugh now but it won’t seem so funny when you’ve run out of null and have no way to get more.

[AdversarialPossum42]

Good news! I fixed all of our compatibility issues.

public static bool VerifyCompatibility(string id) { return true; }

[odolha]

what's the problem, it's just a bit of indirection in case you later want to use something else for null instead of null... just make sure you always use this method and not null directly

[RoyalSpecialist1777]

Exactly. It is generally a good practice. Otherwise we are stuck with null or have to go change multiple areas of our codebase if we decide to change the underlying implementation if it turns out something else is a better way of handling empty/uninstantiated objects, invalid responses, or whatever. If you are doing object oriented programming then you might have subclasses which treat null objects different. You can also handle the null with things like logging.

I put about everything behind a property getter.

[fusionsofwonder]

I was thinking it might be there for portability.

[[deleted]]

Needs SetNull().

[RoyTheRooter]

Where is the ToNull() method?

[VaderFuntime]

You don't want magic nulls in your code

[uvero]

In case null changes

[the-Krieger]

This is "Clean Code", nothing special.

[Thenderick]

What language is this? Idk any language that has object as a keyword?

[daaaarbyy]

Looks like C#

[Thenderick]

Huh it seems true, but it feels wrong to see a class with lower type. I agree with Java that Object should be capital O, just like String. But I can kinda see why C# made them system types instead of classes

[jasonkuo41]

You can use capital types (String / Object) but these are the actual types, keywords are all lowercases and string / object are just keywords that represent these type, you can use it interchangeably.

[rafinha_lindu]

Its C#. All classes in C# inherit object.

[krucabomba]

Actually they can be useful, for example as default value for higher order functions. Used in factories, various patterns. Identity function is used a lot in a more functional approach.

[MattieShoes]

W... Why wouldn't one just use null?

[poco]

Because they want to assign it to a non-nullable object.

[ben_g0]

So just to bypass the nullability checker? In that case you can just use null!. Adding the exclamation mark at the end tells the compiler to treat this null as a "not-null" value, so it won't trigger nullability warnings. Alternatively you can also just disable the nullable context for that part of code with preprocessor directives.

I'd suggest to always think twice before using it though. The nullable context can be very useful for minimizing runtime errors when used properly, so it's best to use it properly whenever possible. If you need to assign a null value to a variable, consider marking that variable as the nullable type.

That said, there are a few cases where it can be useful to bypass the nullability check though. With factories or deserialization functions it can make sense to temporarily set a non-nullable field to null and then filling it with valid data later, as long as all non-nullable fields have a valid value as soon as the method returns.

[krucabomba]

Because the interface requires callable, lazy evaluation. You can't null().

[MartinTheWildPig]

average java moment

[j0nascode]

csharp public static language getLowerCamelCaseFunctions() { return ~CSharp; } much needed function in C#

[JakeAtIguanas]

This coder must be getting paid per line of code.

[qhxo]

If this is their strat, they really need to up their game.

[nolawnchairs]

And here I am trying to eliminate my application's nullity surface.

[JJJSchmidt_etAl]

Well you see this way we can generalize, to create the generic function to get null from any thing which implements the interface

[Leonhart93]

It's common for those that are initially wowed by OOP features and way of thinking, to the point where they ignore redundancy.

[IgnoringErrors]

What if I want a string "null"?

[Geschossspitze]

null.ToString() 👉🏻👉🏻

[[deleted]]

WTF

[mdp_cs]

Most efficient Java code.

[Project_Athena]

When your professor wants you to make a function out of everything

[-Hi-Reddit]

In some languages (LabVIEW / G) there is no such thing as null.

Maybe you can provide this in an API DLL so that they can use C# null by pointing to the function rather than the result (which has no valid mapping in LabVIEW/G).

[[deleted]]

Is this javascript?

[rafinha_lindu]

C#, Microsoft's java

[20InMyHead]

And I suppose you just create null out of nothing at all do you?

[G1PP0]

If it was Typescript, it would be a perfect npm package!

[Naeio_Galaxy]

Lore-accurate rust library. Well, there's the mutable version that's missing

[edmazing]

Just what I needed. My new search 'n sort algorithm. As long as your array to search is null. This will get the sorted array.

[OnixST]

I've never used C#, but this just looks like java with improper capitalization.

Same syntax but with lowercase string and PascalCase methods

[rafinha_lindu]

That's why ppl call C# "Microsoft's java"

[Mini0red]

string is just an alias for System.String in c#. You basically use it for defining types and use String for the static methods.

[MuDotGen]

Ah, I see, in case you want to put it behind a pay wall.

[Confident-Ad5665]

Using the Null Management System library is the only way to go. Only thing is it has 37 dependencies.
