Have the jar now, using IntelliJ Ide, what do I do with the jar if you don't mind?

silent timber What's the event for opening an enderchest?

silent timber Mar 29, 2022, 12:48 AM

#

Thanks

#

Just compare inventory type?

pliant oyster Mar 29, 2022, 12:48 AM

#

check if the inventory is a enderchest

#

yeah

desert musk Mar 29, 2022, 12:53 AM

#

hasty prawn Add it as a dependency

didn't work, probably doing it wrong

#

the thing is i'm already using a jar

#

it just doesn't have that class

hasty prawn Mar 29, 2022, 12:56 AM

#

You're definitely doing it wrong then

desert musk Mar 29, 2022, 12:56 AM

added it as a module, added an artifact

that's all i did

What are you trying to do

vague oracle Mar 29, 2022, 1:10 AM

I think you need to cast it to a living entity

arctic moth Mar 29, 2022, 1:25 AM

hasty prawn isSnowy

in what

#

block, blockdata, etc.?

hasty prawn Mar 29, 2022, 1:26 AM

#

BlockData I think

arctic moth Mar 29, 2022, 1:26 AM

#

nope

#

not in block either

hasty prawn Mar 29, 2022, 1:29 AM

#

It's in Snowable

#

Which extends BlockData

#

So you have to cast

desert musk Mar 29, 2022, 1:32 AM

#

Ok how could i be doing this wrong

#

the API has worked perfectly for me until now

arctic moth Mar 29, 2022, 1:32 AM

#

hasty prawn It's in Snowable

whats with all the Levelable and Snowable stuff bruh coudlnt they just like do it in a class called Grass or smth

desert musk Mar 29, 2022, 1:32 AM

#

i installed a new craftbukkit jar and it's literally the same

arctic moth Mar 29, 2022, 1:33 AM

like GrassBlock could have functions that Snowable currently has

and Water could have the Levelable stuff

If you built it properly with build tools all you have to do is add it as a dependency in your pom.xml if you are using maven

#

or gradle.something if you are using gradle

desert musk Mar 29, 2022, 1:35 AM

#

shit

#

i thought that was the case but i couldnt find any pom.xml stuff for craftbukkit

#

thank you though

#

yeah how am i supposed to add it to pom?

#

do I just have to paste this into it? https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/pom.xml

#

i don't understand

vague oracle Mar 29, 2022, 1:40 AM

you can add it to a folder in your project and use

tender shard Mar 29, 2022, 1:48 AM

yes I also did it like that 1-2 years ago

but maven throws a ton of warnings if you do it like that

#

YamlConfiguration yaml = new YamlCOnfiguration();

then save it to a file

#

tender shard yaml.set("players." + uuid2,yourListOfUUIDsForSecondPlayer);

important: all the UUIDs must be strings for this to work

silent timber Mar 29, 2022, 2:19 AM

#

and then reading it, how would i get the list of uuids back into a list?

tender shard Mar 29, 2022, 2:20 AM

#

for example this (one second, gotta type it quickly)

#

imagine you have this:

#

players:
  firstplayer:
    - aa00000151251258612581528615
    - aaaa725115723651976135976153

then it's actually a List<String>. but you can just use a stream->map to turn it into a list of UUID objects:

List<UUID> uuids = getConfig().getStringList("players.firstplayer").stream().map(UUID::fromString).collect(Collectors.toList());

silent timber Mar 29, 2022, 2:22 AM

Probably best to figure out why .teleport isn't working for you

#

It is rather unlikely that the logic itself is broken

visual tide Mar 29, 2022, 4:57 AM

maybe your teleport is in an if statement that isnt actually gonna ever be true

Well that's why it can't teleport

#

You can't teleport entities with passengers I believe

You gotta dismount, then teleport the entity, then teleport its passenger back to it and re-mount it

#

It's very annoying

But it's not ".teleport not working" and you should have been more specific

Hi, I try to create a new Command with the CommandExecutor in Spigot for 1.18.1. I just created my first command and now I want to create a command with extra args. How can I cast a String Argument to a Material.X?

waxen plinth Mar 29, 2022, 5:19 AM

Material.valueOf(String)

All enums have valueOf for that

Material.matchMaterial might also work out well for you

waxen plinth Mar 29, 2022, 5:20 AM

Careful though, because it throws an exception if a value is not matched rather than returning null

Not 100% clear though

glass mauve Mar 29, 2022, 5:23 AM

#

yea I read the docs, getMaterial needs the precise name and matchMaterial will format b4 checking:
This is a match lookup; names will be stripped of the "minecraft:" namespace, converted to uppercase, then stripped of special characters in an attempt to format it like the enum.

based on the fact that playerrespawnevent doesn’t implement cancelable, i’m not really sure - try getting the players location when the event is called and see where it is

otherwise you might need to have a death listener and save the locations

then if ur using intellij make it into a live template if ur gonna reuse code

why do u NEED it to be anything else

Is it possible to do this?

I honestly dont understand

it is not possible to have a java class name dynamic

without it being extremely counter-intuitive

quaint mantle Mar 29, 2022, 8:29 AM

#

Maybe the name of the class in which extends JavaPlugin?

low temple Mar 29, 2022, 8:30 AM

Yeah you can’t change that

There is literally no reason for it to be dynamic

#

You haven’t explained an actual reason as to why you need this to be possible

quaint mantle Mar 29, 2022, 8:31 AM

#

This is something like a GUI library

low temple Mar 29, 2022, 8:31 AM

#

But why do you need it to be dynamic

#

It makes zero logical sense to make it dynamic

#

Also in a library you wouldn’t have a plug-in instance class in a library, also wouldn’t make sense

quaint mantle Mar 29, 2022, 8:32 AM

#

I just need to make everything work when copying GUI classes to another project where the name of the main class is different

low temple Mar 29, 2022, 8:32 AM

#

Ok so do what I said before, pass the plug-in instance into the ChestGUI class

#

Best way to do it

quaint mantle Mar 29, 2022, 8:33 AM

#

It will not be convenient all the time

low temple Mar 29, 2022, 8:33 AM

How…?

quaint mantle Mar 29, 2022, 8:34 AM

#

Plugin plugin = OwnExperienceWorld.getPlugin(OwnExperienceWorld.class);
plugin.getServer().getPluginManager().registerEvents(this, plugin);

#

It works, but if I suddenly move this class to another project, it won't work

low temple Mar 29, 2022, 8:34 AM

#

Yeah because u need to pass it as an parameter

#

Create a plugin parameter in ur default constructor and set the plugin variable to it

quaint mantle Mar 29, 2022, 8:35 AM

#

How can I, for example, get the name of the class in which JavaPlugin is extended

low temple Mar 29, 2022, 8:35 AM

#

Bro, you really shouldn’t need to

#

I’m telling you, pass the instance

#

There is zero reason why you would ever do that

#

You logically can’t without jumping through 70 different wacky programming hoops

quaint mantle Mar 29, 2022, 8:37 AM

#

I just thought it was possible to get the name of the class in which JavaPlugin is extended.

#

Bukkit.getServer().getPlugin(String name);

low temple Mar 29, 2022, 8:38 AM

#

Not really, not without passing the instance

#

And if you pass the instance there’s no reason to do it the way you suggested

#

Bro please, just pass the instance, it’s not more complicated

quaint mantle Mar 29, 2022, 8:39 AM

#

Okay, thanks

buoyant viper Mar 29, 2022, 8:43 AM

#

so what could be done actually is something like

#

in the constructor of ChestGUI, u add a param like Class<? extends JavaPlugin> pluginCls and then in the constructor method u do JavaPlugin ownerPl = JavaPlugin.getProvidingPlugin(pluginCls);

#

not necessarily

low temple Mar 29, 2022, 8:50 AM

#

Basically the same thing

to pass the actual object vs the class

#

oh wait yeah u could do just JavaPlugin then

low temple Mar 29, 2022, 8:51 AM

#

true but wouldnt it just make sense to just to JavaPlugin

buoyant viper Mar 29, 2022, 8:51 AM

#

yeah bc then it avoids having to do a lookup every time u make a gui

low temple Mar 29, 2022, 8:51 AM

#

unless you only need the class, even then you can get it from the object

buoyant viper Mar 29, 2022, 8:52 AM

#

ur getting the object from the class in the end so if u could provide the object then u bypass a whole step

low temple Mar 29, 2022, 8:52 AM

#

he just needs the plugin instance, the class is irrelevant since its used to get the plugin instance

buoyant viper Mar 29, 2022, 8:52 AM

#

yeah

#

for convenience i think mine would win since u wouldnt need to worry about having the instance stored somewhere, could literally just do like new ChestGUI(other params, MainPluginClass.class), but for optimization (and probably sanity), ur idea is the way to go

just place an armorstand when the skull head is placed

#

when head is broken, remove the armorstand too

yea, but then I need to handle like dozen of events of block destroy

sharp flare Mar 29, 2022, 9:45 AM

cache the holograms

use block location as key

clear raptor Mar 29, 2022, 9:45 AM

on that place anymore

Use #setPersistent(true) and #setRemoveWhenFarAway(false)

clear raptor Mar 29, 2022, 9:47 AM

for the armorstand?

and you can try saving the hashmap inside a file

onDisable

and restore it onEnable

yea... and that way I can also remove armorstands when head is no longer on that place

you created a new itemstack, but never initialized wand.

doesn't matter if you never assign it to wand

would have to be
wand = new ItemStack....

you just never initialize wand

it will probably just delay the water by flowing there by 1 tick

well u could also work arround that

clear raptor Mar 29, 2022, 11:00 AM

#

I think that it is not a big problem

tall dragon Mar 29, 2022, 11:00 AM

#

by checking the neighbors of the To block

#

but if ur not bothered by it 🤷‍♂️

clear raptor Mar 29, 2022, 11:00 AM

thats too much work for no reason I think....

#

Hopefully same will work with piston

tall dragon Mar 29, 2022, 11:01 AM

idk why there is no BlockBreakNaturallyEvent tbh

but there probs is a good explaination

clear raptor Mar 29, 2022, 11:02 AM

set the block type to air and cancel the event

if you name stuff like that while youre working on ur code

stuff will get messy

#

i would even name block "blockAffected"

grim ice Mar 29, 2022, 11:08 AM

#

clear raptor ```java boolean playerHeadBreak(Block block){ if(!isMyCustomBlock) ...

so its not a boolean

clear raptor Mar 29, 2022, 11:08 AM

#

ehh... wait

grim ice Mar 29, 2022, 11:08 AM

what is it supposed to do anyways

not complete code it can be boolean if he send the modifiers

and return type if its not void

clear raptor Mar 29, 2022, 11:09 AM

clear raptor ```java boolean playerHeadBreak(Block block){ if(!isMyCustomBlock) ...

sharp flare Mar 29, 2022, 11:09 AM

what, u using wrapper classes for the return type?

clear raptor Mar 29, 2022, 11:10 AM

#

pseudo code lol

#

ignore details 😄

sharp flare Mar 29, 2022, 11:10 AM

#

aight

clear raptor Mar 29, 2022, 11:10 AM

#

I use this method on all drop events

#

so I not dupe code...

#

thats why it is weird a little

#

renaming it to dropPlayerHead 😄

sharp flare Mar 29, 2022, 11:11 AM

#

why not just use only the

      return false;

#

to determine if its the right block inside the event listener

clear raptor Mar 29, 2022, 11:12 AM

#

sure that is what I am doing 😄

#

But after that I drop my custom item and want to cancel drop of original one

#

I have custom PLAYER_HEAD item with custom NBT Compound... When I place it, NBT gets saved into PDC and then retrieved in every block break event so it can be used to create the original item again.

sharp flare Mar 29, 2022, 11:13 AM

#

does your head drop the custom one when broken without any of these checks?

clear raptor Mar 29, 2022, 11:14 AM

#

It does not thats why I need to check for every single one block break event what drops it

#

Because I cannot loose the NBT

#

and still give players ability to place and destroy the special head

sharp flare Mar 29, 2022, 11:14 AM

#

so its making a new custom itemstack every break, I see

clear raptor Mar 29, 2022, 11:14 AM

#

Yes

#

Or I can edit existing one?

#

I think that block.getDrops() is immutable right?

#

yea. it is...

sharp flare Mar 29, 2022, 11:17 AM

#

you can edit existing drops

#

it returns a collection I think

clear raptor Mar 29, 2022, 11:18 AM

#

So I can remove the original item and put there my new one right?

#

does not work...

block.getDrops().clear();
block.getDrops().add(myCustomItem);

And it still drops the original one...

wide coyote Mar 29, 2022, 11:20 AM

#

isnt there a setDrops method?

clear raptor Mar 29, 2022, 11:20 AM

#

nope

wide coyote Mar 29, 2022, 11:20 AM

#

ah i guess it was in a event then

clear raptor Mar 29, 2022, 11:21 AM

#

yea... because BlockPistonExtendEvent and BlockFromToEvent are not block break events, they cannot alter drops

#

it should work for other events, tho

#

haha lol... behaving weird when there is a block between head and piston 😄

#

why it does not play here?

#

its not virus I promise 😄

try BlockDropItemEvent it has a method that returns an mutable list of drops

Anyways yeah that's some interessting behaviour

sharp flare Mar 29, 2022, 11:25 AM

clear raptor does not work... ```java block.getDrops().clear(); block.getDrops().add(myCustom...

its actually you modify the drops and drop it naturally

chrome beacon Mar 29, 2022, 11:25 AM

#

I'd say it looks fine

#

Maybe call update on the piston after you remove the head

clear raptor Mar 29, 2022, 11:26 AM

#

how?

#

cast block to piston or something like this?

sharp flare Mar 29, 2022, 11:26 AM

#setDropItems(false) then modify the drops, drop it naturally

clear raptor Mar 29, 2022, 11:26 AM

Actually just use this https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/block/data/type/Piston.html

Piston (Spigot-API 1.18.2-R0.1-SNAPSHOT API)

clear raptor ```java boolean playerHeadBreak(Block block){ if(!isMyCustomBlock) ...

^^

#

ah

sharp flare Mar 29, 2022, 11:28 AM

#

clear raptor ```java boolean playerHeadBreak(Block block){ if(!isMyCustomBlock) ...

you can just replace previous drops instead of clearing it

wide coyote Mar 29, 2022, 11:28 AM

#

wide coyote try BlockDropItemEvent it has a method that returns an mutable list of drops

.

sharp flare Mar 29, 2022, 11:29 AM

#

actually you don't even need to do #clear on that since you set the block type to air and cancelled the event. since u make drops out of an new itemstack

#

#setDropItems(false) then drop the new itemstack naturally saves you some lines

clear raptor Mar 29, 2022, 11:30 AM

#

wide coyote try BlockDropItemEvent it has a method that returns an mutable list of drops

this does not get fired on my server

#

Same with the Paper's BlockDestroyEvent

#

Yea... BlockDropItemEvent is called only for items destroyed by player, not naturally

clear raptor Mar 29, 2022, 11:41 AM

#

chrome beacon Actually just use this https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/block...

This does not work... When I set it, piston just loose movable part and block not move.

chrome beacon Mar 29, 2022, 11:41 AM

#

Hm alright

clear raptor Mar 29, 2022, 11:41 AM

#

I must somehow cancel the drop and not the piston event

#

Seems like no other way here

chrome beacon Mar 29, 2022, 11:42 AM

#

Try setting the head to air

clear raptor Mar 29, 2022, 11:42 AM

I thought it was working well?

give me second 🙂

works fine when head is in first place tho

#

Thats the current problem 🙂 everything else is solved

This is very promising: https://papermc.io/javadocs/paper/1.18/com/destroystokyo/paper/event/block/BlockDestroyEvent.html

you want the first one to make the stone move?

clear raptor Mar 29, 2022, 11:53 AM

thats normal behavior

video looks good to me

why?

sharp flare Mar 29, 2022, 11:53 AM

#

whats the issue in the video?

clear raptor Mar 29, 2022, 11:54 AM

#

stone should move to the place of dropped head

#

sharp flare Mar 29, 2022, 11:54 AM

#

not sure if thats a vanilla mechanics or it can be changed

clear raptor Mar 29, 2022, 11:54 AM

#

it is

#

vanilla mechanic 🙂

#

it does not move the block because I cancelled the piston event

#

but If I not cancel it, I also get the default head drop I dont want

#

See the dilema?

sharp flare Mar 29, 2022, 11:56 AM

#

cancelling it is the best option ig, as long as the relative block is the custom head

clear raptor Mar 29, 2022, 11:56 AM

#

Yea... It works fine when piston directly push the head

#

but indirectly it gets broken

young knoll Mar 29, 2022, 11:56 AM

#

Break the head manually instead of cancelling?

clear raptor Mar 29, 2022, 11:56 AM

#

breaking head means setting it to AIR

#

thats what I did...

young knoll Mar 29, 2022, 11:57 AM

#

And that stops the block being moved?

clear raptor Mar 29, 2022, 11:57 AM

#

yea

young knoll Mar 29, 2022, 11:57 AM

#

Weird

clear raptor Mar 29, 2022, 11:58 AM

#

yes... I even removed the event cancel

#

And still...

young knoll Mar 29, 2022, 11:58 AM

#

You could mark the location and then listen for the ItemSpawnEvent

#

And compare locations

clear raptor Mar 29, 2022, 11:59 AM

#

wait a minute...

#

Oh I am stupid.. I miss looked the right event...

#

It seems to work when I not cancel the event and just replace block with AIR

#

yes 😄 it works...

sharp flare Mar 29, 2022, 12:00 PM

#

yeah cuz u cancel the piston event

#

this is why I get kinda lost

clear raptor Mar 29, 2022, 12:00 PM

#

yea but I thought for some reason that if I not cancel it it drops default head

#

Sorry for that

#

Fine 😄 So I covered BlockBreakEvent, BlockDestroyEvent, BlockFromToEvent and BlockPistonExtendEvent.. Hopefully there is no other way of destroying the block 😄

sharp flare Mar 29, 2022, 12:01 PM

#

sharp flare set the block type to air and cancel the event

clear raptor Mar 29, 2022, 12:02 PM

#

Yea but you said cancel event

sharp flare Mar 29, 2022, 12:02 PM

#

for the block break event

#

where did u use setType air then

clear raptor Mar 29, 2022, 12:02 PM

#

block break event does not fire when piston removes item

#

@EventHandler
    public void onBlockPistonExtend(BlockPistonExtendEvent event) {
        for(Block block : event.getBlocks()){
            if(dropPlayerHead(block)) {
                block.setType(Material.AIR);
            }
        }
    }

#

this does the trick...

#

If we drop custom head, then we set the block to AIR

sharp flare Mar 29, 2022, 12:03 PM

#

aight now im sure i got lost last time cuz of the two events

clear raptor Mar 29, 2022, 12:03 PM

you would just need the increment and direction or not?

a vector can either be a point V(x|y|z) or a direction vector V-> x y z.

if u know ur orig vector and u know the distance why dont u just add it to the point and keep the directional vector untouched?

granite owl wanted vector * r = orig vector like ive said in the beginning

r is the distance i assume?

granite owl Mar 29, 2022, 1:38 PM

#

yes

#

it creates a new vector

#

which is the many of r of the orig point

quiet ice Mar 29, 2022, 1:38 PM

#

desert musk which is better? IntelliJ remote development or github

what is the diff?

desert musk Mar 29, 2022, 1:38 PM

#

quiet ice what is the diff?

no clue

valid solstice Mar 29, 2022, 1:38 PM

#

granite owl which is the many of r of the orig point

ok ill try that, thanks

quiet ice Mar 29, 2022, 1:38 PM

#

Do you mean Github desktop with github?

desert musk Mar 29, 2022, 1:38 PM

#

yeah

#

intellij can link with git

quiet ice Mar 29, 2022, 1:39 PM

#

Oh then no idea

#

I always used the CLI because my IDE sucks at supporting signing commits

granite owl Mar 29, 2022, 1:39 PM

#

@valid solstice thats the formula to determine wheter or not it is parallel sorry

#

which needs to return true results

valid solstice Mar 29, 2022, 1:39 PM

oh

Yeah i got the github project onto my other computer but it sends tons of errors when i try to build it

valid solstice Mar 29, 2022, 1:40 PM

#

well im trying to find the parallel vector of x

desert musk Mar 29, 2022, 1:40 PM

#

mainly that “no goals have been specified for this build”

quiet ice Mar 29, 2022, 1:40 PM

#

Do you use maven/gradle?

desert musk Mar 29, 2022, 1:40 PM

#

maven

granite owl Mar 29, 2022, 1:41 PM

#

i think uhmm a-> + u-> * s + v-> * t @valid solstice

#

a being ur vector of the starting point

#

forget it needa get home first to check it properly

valid solstice Mar 29, 2022, 1:42 PM

#

um alright ill look more into that

quiet ice Mar 29, 2022, 1:42 PM

#

Well the formula to create a paralell function from function f(x) = mx + b would be p(x) = mx + b + (1 - 1/m²) or something like that idk

#

actually no, that wouldn't work

granite owl Mar 29, 2022, 1:44 PM

#

tbh ik its u-> = v-> * r to determine wheter or not theyre parellel

#

but i forgot how to derrive the formula to create one from it

valid solstice Mar 29, 2022, 1:45 PM

#

i'm thinking that a good way to make this possible is to get the direction of the location

tender shard Mar 29, 2022, 1:45 PM

#

are there any enum classes built in to java?

quiet ice Mar 29, 2022, 1:45 PM

#

To determine whether they are parallel it is just m1 = m2, no?

valid solstice Mar 29, 2022, 1:45 PM

#

add or subtract 90 to it to get the parallel vector points, then just multiply it by (x) for the distance and multiply it again from the original direction to form the line

quiet ice Mar 29, 2022, 1:45 PM

#

tender shard are there any enum classes built in to java?

Probably yes

#

StandardOpenOptions is one I know of

tender shard Mar 29, 2022, 1:46 PM

#

quiet ice Probably yes

do you know any? 😄

#

okay thanks

quiet ice Mar 29, 2022, 1:46 PM

#

StandardCopyOptions is another

tender shard Mar 29, 2022, 1:46 PM

#

yes I'll use that

#

I just need some enums for a unit tests and didnt want to use Material etc since they are being removed SOME time

granite owl Mar 29, 2022, 1:46 PM

#

quiet ice To determine whether they are parallel it is just m1 = m2, no?

nah

quiet ice Mar 29, 2022, 1:46 PM

#

Alternatively, open up the javadocs and check which classes extends Enum

granite owl Mar 29, 2022, 1:46 PM

#

if thats the case you compare a set point a with a wanted point b

#

and then theyre identical

#

if thats true

#

u have to add the multiplier factor if theyre parallel but not identical

quiet ice Mar 29, 2022, 1:47 PM

#

I mean any linear function has to be f(x) = mx+b. b's value does not matter for determining paralellity

#

In other words, f'(x) = p'(x). Since f'(x) = m, only m matters

granite owl Mar 29, 2022, 1:48 PM

#

to dertermine if theyre parallel u have to derterime if theyre a factor of each other

#

sorry hard to translate

all of the ones that use EntityX in them use deprecated methods i think

The stupid thing is that I cannot deal with vector properly yet, so I try to translate them to linear functions

valid solstice Mar 29, 2022, 1:51 PM

#

quiet ice Vectors are Q1+ maths or physics afaik

i have been taught about vectors during my 8th grade physics but these are just simple multiplication/addition operations

#

plus they're 2 dimentional vectors, so exploring 3d vectors are a new thing to me

quiet ice Mar 29, 2022, 1:52 PM

#

Actually math vectors are different to physics vectors - so disregard my previous statement

#

Oh right, vectors in mc are 3 dimensional 🤦

valid solstice Mar 29, 2022, 1:53 PM

#

anyways i think i may have found a way to make this possible using the locations yaw instead of dealing with the vector itself

#

still going to experiment with it though

you cant do that

#

a vector is an array

#

its just a different word for array

quiet ice Mar 29, 2022, 1:54 PM

#

Yeah, but a physics vector is a linear function usually

#

It's really stupid that physics and mathematics use vector for two different things.

#

Technically they are kinda similar, yes - but noone will teach you those similarities

for my lib I need to instantiate collections generically. I have until now just used CollectionClazz.getConstructor().invoke(). However, that won't work if the constructor requires an argument, e.g. EnumMap requires an Enum.class as parameter. I have now just added a method that doesn't only take a collectionClazz, but also a collectionSupplier, like this:

    /**
     * Turns an existing DataType into one that holds a {@link Collection} of the same class
     * @param collectionClazz The {@link Collection} to use.
     * @param collectionSupplier A {@link Supplier} that returns an empty instance of the given Collection class.
     * @param type The existing DataType
     */
    static <C extends Collection<D>, D> CollectionDataType<C,D> asGenericCollection(final @NotNull Class<C> collectionClazz,
                                                                                    final @NotNull Supplier<C> collectionSupplier,
                                                                                    final @NotNull PersistentDataType<?, D> type) {
        return new CollectionDataType<>(collectionClazz, collectionSupplier, type);
    }

Anyone maybe have an easier idea?

#

for example getting an EnumMap would now look like this:

    /**
     * Creates a DataType holding an {@link EnumMap} of the given Enum Class and DataType
     * @param enumClazz Enum class
     * @param valueType Existing DataType for the map's values
     */
    static <K extends Enum<K>,V> MapDataType<EnumMap<K,V>,K,V> asEnumMap(final @NotNull Class<K> enumClazz,
                                                                         final @NotNull PersistentDataType<?,V> valueType) {
        return new MapDataType(EnumMap.class, (Supplier<EnumMap>) () -> new EnumMap(enumClazz),DataType.asEnum(enumClazz), valueType);
    }

quiet ice Mar 29, 2022, 1:59 PM

#

I'd just use a supplier

#

unless the class instance is required

ivory sleet Mar 29, 2022, 1:59 PM

#

I mean you could pass a Collector<T,A,R>

#

and then handle that properly ofc

tender shard Mar 29, 2022, 1:59 PM

#

quiet ice unless the class instance is required

a collector?

#

wrong reply

#

how would a collector help here

quiet ice Mar 29, 2022, 2:00 PM

#

I.e. so a call is something like asGenericCollection(() -> new EnumSet(Enum.class), type);

ivory sleet Mar 29, 2022, 2:00 PM

#

you asked for easier ideas?

tender shard Mar 29, 2022, 2:00 PM

#

yes but I have no idea how it would work using a collector 😄

#

so could you explain please how it'd work? 😄

ivory sleet Mar 29, 2022, 2:01 PM

#

ehm well read this:
https://www.baeldung.com/java-8-collectors
but hopefully you ought to be familiar with what it can do as I hope you've for instance touched Stream::collect

tender shard Mar 29, 2022, 2:01 PM

#

thx. Of course I've used collectors before but I've never looked at their source nor did I ever wonder how they work
