Are Reals leaking?

[CoLd Bon3]

Hi! I want to ask if Reals leak, and if they leak - what is the code to remove them...

• Custom script: call DestroyReal (GetLastCreatedReal())

Just kidding
No, they do not leak, neither integers do.

Neither booleans, and you can not do anything about strings. They create small leak, although there is no way for removing them.
This should be your next lecture.

Here is a great rule for leaks.


If you create it, it will stay until it is removed. For example, creating a group or a unit. If you no longer reference something and you don't remove it, that's a leak (it's sitting around in your map). For example, enumerating through a group and then never destroying that group.

If you reference something that is created and can be destroyed, that reference (the pointer) will leak. If it didn't leak, there would be a possibility of a unit pointer referencing a timer-

local unit u=CreateUnit()
local timer t
call RemoveUnit(u)
set t=CreateTimer()
//u would reference t if pointers were recycled regardless of what was referencing them

So yes, you have to null your pointers, otherwise they are never reused and the handle table (a hashtable) gets cluttered.

Code, boolean, string, real and integer are the only things that don't leak.
You wouldn't know what a "code" type is if you work in GUI, but the rest
are all familiar.

Thank you guys!
