Garbage Collection

[cbk1994]

Yumm, garbage. Someone care to explain to me what all the garbage collection features GS2 has?

Also, do references exist in GS2? For example, say you do this:

PHP Code:

n = new TStaticVar(); 


So, a variable n is created; a TStaticVar() is also created, in the memory of the server/client. Let's call the memory address 102 (an example). So n holds a reference to address 102. Now what if we do this:

PHP Code:

n.var1 = "blah";
x = n; 


Now will x have a reference to 102? Or does it create a new TStaticVar, and then copy the vars? What if I were to do something like this?

PHP Code:

//#CLIENTSIDE
function onCreated()
{
  x = new TStaticVar();
  y = x;
  y.var1 = "blah";
  echo( x.var1 );
} 


What does that echo? I can't get on RC now, and I probably won't be able to for a while.

Can anyone please clear this up for me?

Then, if I go:

PHP Code:

x = NULL; // Not destroying the object, dropping the reference
y = NULL; // Likewise
// Now, as all references are dropped, is the TStaticVar dropped from the memory (collected by garbage collection)?
