Unset Gamecache Variable Returns What?

If I try to retrieve data from a gamecache that I've never stored anything into, what will I get returned? 0? null? error?


What would i be assigned as if I never stored anything as "Something", "Something"?

I tried a search but didn't find anything about it.

EDIT:
I think I actually found something related to this problem, however, it says GetStoredXXXX returns 0. How does that work for strings?

I think for integers it returns 0.
You should just test it by yourself.

There is also a function that checks if a value is set for the key pair:
HaveStoredInteger/HaveStored<Type>

Yes I noticed that, but what does strings return?

Hmm I'll just test it myself.

EDIT: It returned "", thanks for the tip on the functions though

There is some fun with string return.

It actually return null as string.

Nice to know it doesn't crash. Could be useful information for passing data between AIs through gamecache.

There is PriceServer and PriceServerAI on wc3jass.com for this.

Passing data is not instant.

Cached values default to null, 0, and "" respectively.
