SOLVED A simple question about method names in derived classes; why are they called "getBlahBlah()"

[MSpace-Dev]

Hey everyone,

 

So.. I have always wondered why, when you want to set something like, say, an item's rarity. You'd use the method getRarity() to SET the rarity of that item. Why are these methods named like this? Is it because when the code compiles, the code that puts it all together looks through everything and GETS the values from these methods, and that's why you override these GET methods? Just been a little curious about this.

I did also notice a little inconsistency though. Like when you want to set a block's light level, the method you override is called setLightLevel()...  are there any rules to know when to use the GET method to set something and the SET method to set something?

Alright, then can you explain to me what calls GetRarity()? Cause everything you've said there I've already said above, but thanks for clarification on that part. Just need to know the missing piece of the puzzle, which is, what is calling these methods?

[MSpace-Dev]

I have tried to look, but I just get into a loop of going back and forth. I cannot find any other classes that use the method getRarity so, I cannot figure out what calls these methods, hence why I came here to ask the question. "Use your IDE." isn't super helpful. But I understand that you're trying to get people to figure things out for themselves, just... in this case, I never found what I was looking for. I also did find something called IForgeRegistryEntry so yeah...

First off, I manage to find the super method

public EnumRarity getRarity(ItemStack stack)
    {
        return stack.isItemEnchanted() ? EnumRarity.RARE : EnumRarity.COMMON;
    }

Where do I go from there? (I'm ctrl+clicking things, btw) and I use IntelliJ IDE

When I ctrl+click getRarity, it just takes me back to where I've overridden it, and not to where it gets called elsewhere, cause there is no 'elsewhere'

Look at this picture:

Look at the picture, that's exactly what I did. I clicked on Find Usages (Pressing Alt+F7) and that picture shows the results. A result of it only being used in my class. And when I say that I've found the super method, that method is the super method from MY derived class. What I'm saying is that I managed to get to the class where getRarity is declared.

This takes me to the Item class where it's declared.

Never realized I was in Project Files.

Anyways, I have found it being decalred in ItemStack, and other classes. Except these aren't overriding anything, they're declaring new methods of it? I can't find what actually "calls" it. Perhaps if you tell me the answer, I'll be able to understand what's happening here better.

Sounds like you searched for references writing the hierarchy, rather than everywhere.

Oh, I understand now. Yeah. I thought Item extended ItemStack or viceversa, which is why I was expecting to find an @Override above one of the methods. Yeah, this makes perfect sense.

That would never make sense.

I'm still grasping what each of these things do. Give me a break. Thanks for the help though guys!
