Does I2S leak? Do non-local strings need to be cleaned up?

[afisakov]

I have a number of lines of the form:

call DisplayTimedTextToPlayer(GetOwningPlayer(GetTriggerUnit()),0,0,1.00,(GetHeroProperName(GetTriggerUnit())+": |cffff0000quest 1 reward: "+I2S(g)+" gold, "+I2S(exp)+" exp|R"))

this is an example but many of them are in same format. I already display to player to avoid player group leaks.
Does anything else from this line leak and need to be cleaned up?

P.S. "g" and "exp" are local integers

I asked because I saw some map makers define the string to a variable and then set it to null later, but I never knew why or if that was needed.

only handles could make leaks. strings, obviously, are not handles

You don't need to null strings. Strings can leak, sort of. They are actually all stored in a table, but the memory usage is so insignificant that you don't need to worry about it. Plus, it is helpful if you later want to reuse that string.

Also, there is no way to clear that table, so again you don't need to worry about it. Assigning it to a variable and nulling it is pointless.

thank you very much for the replies. that makes one less thing to worry about on this map.
