[1.15]Custom Config Complex Data Structures

Hi,

my mod uses an ore distribution to determine with which block it should replace.

Currently I use as a default this table where each entry in the matrix is probability adding to 100% for each y-lvl except where my mod does not replace the block::stone

y - level | coal | iron | gold | lapis | redstone | diamond

>110     0    0     0     0      0       0

>60      1    0     0     0      0       0

>30     50   50     0     0      0       0

>15     25   50    15     10      0       0

>5      20   40    15     7      13       5

>0       0    0     0     0      0       0

For my config I want to be able to edit this matrix where the y-level border is, the blocks and the probability linked to them.

Using nightconfig and ForgeConfigSpec (.define(String path/name, T defaultValue, Predicate<Object> validator))

I would implement my Data Structure T as an

HashMap<Integer,List<HashMap<String,Float>>>

with

HashMap<y-level,List<HashMap<ResourceLocationofBlock,probability>>>

(ResourceLocationofBlock as "namespace:block" like "minecraft:coal_ore")

,a custom Supplier giving the table above and a custom Predicate checking the ResourceLocationofBlock, the probabilty and wether all y-values are coverd.

My Questions:

1. Can I use a HashMap? in other words do I need to use a HashTable for thread safety
2. Can I use ResourceLocation.isResouceNameValid(String) when my Config loads? (Using CLIENT_BUILDER since @OnlyIn(Dist.CLIENT))
3. Is there another way to allow an user to add custom blocks to my config? (My way would be an Array/List which is typed in the Config)
4. Is this ForgeConfigSpec the way to do Config in Forge 1.15?

Edit: changed y-level to Integer instead of String
