I am rewriting my code to work faster, and right now I am in bit of a problem.

Situation is that I have this table containing items, and I am in need of deleting a specific one of them out.

However, problem is that I don't have access to the table at that point, but only to the item.

As in situation is:

Code: Select all

Function MyVar(Item)
Delete Item from Mytable?
EndFunction

mytable = {}

ItemVar = Mytable[n]
somefunc(ItemVar)

Is there any way I can either delete this ItemVar from MyTable in this SomeFunc() situation?, or way to find out in what index ItemVar resides in MyTable?

edit:
Comes to my mind that ItemVar is pointing to some certain memory address, as far as I have understood. Therefore, is there any command to make that target memory address NIL? would something like that work?

If Mytable[n] isn't a sub-table, there's no way to find relationship between ItemVar and it.

If Mytable[n] contains a string, number, or any other kind of data that is not a table, ItemVar stores an independent copy of the data from Mytable[n]. If you delete the whole Mytable table, ItemVar still has the value stored on it and it doesn't disappear. ItemVar has no clue where it got the data in it, source isn't marked anywhere. Doing "ItemVar = Nil" removes the ItemVar variable contents, but doesn't touch to the original table.

sorry my mistake in the example. ItemVar is a table, not variable.

Code: Select all

Function somefunc(Item)
Delete Item from Mytable?
EndFunction

mytable = { [1] = {},
	[2] = {}
		  }

ItemVar = Mytable[n]
somefunc(ItemVar)
