[1.20.4] custome class to read and write nbt files now demands an NbtAccounter object ???

[perromercenary00]

good days 
still working on the briefcases 
now i want to save/read inventory presets from tangible nbt  files 
i have and old class i use to read and write nbts for structures and wanna dust out 

 

step by step goes to here 

	return NbtIo.readCompressed(rs.get().open() );// <-- this is the error
	

the thing is 

NbtIo.readCompressed now demands a second parameter from the class NbtAccounter and that seems like a kind of limiter for the nbt file size 
i dont get what the numbers are for 
is good if i just made an NbtAccounter.unlimitedHeap() and call it a day 

//or this piece of code gonna blowsdown something further in the way 
return NbtIo.readCompressed(rs.get().open(), NbtAccounter.unlimitedHeap() );// <-- this is the error

 

can someone point me a git hub where they use this or du something similar ?
