Would this cause a memory leak?

[marfit]

I am trying to clean up a table. Because iterating through it is too difficult (see Efficiently iterating through 3D array), I intend on simply setting its variable to nil, see:

local Table = {{{1,2,3},{1,2,3}},{{1,2,3},{1,2,3}},etc.}

Table = nil

Would the garbage collector clean up Table, and all the tables/values stored in it? Or would those values float in memory causing a leak?

Can weak values in a table avoid memory leaks from lost table refs?

Hi all, so I know that it usually isn’t best practice to “clear” a table just by removing reference to it like so: local t = { CFrame.new(), CFrame.new(), CFrame.new() } t = { } Because that wouldn’t free the memory the objects use in the table. I know the old t will eventually be garbage collected, but from what I know, the object references it contained won’t be. So here is the question: would making the values weak avoid the memory leak? For instance, how would this be better than the fi…

TL;DR no

Tables will only cause memory leaks if you reference roblox instances, and the table does not get GCed

Thanks for the help. I wasn’t exactly sure whether the table counted as a reference or not.

It does, but if the table has no more references and the objects in it don’t either, the objects including the table are eligible for GC
