Hi,
I have something like this :
var myTestClass=Class.create({
initialize:function(opt) {
this.child=null;
// do stuff that uses mem
// like create and show divs
// and so on
},
myFnc:function(param) {
}
});
With this class I build a 'tree'.
(
in real life I use other code to do this : the child is assigned
from within the class, but that doesn't matter for my question
)
var myOne=new myTestClass();
myOne.child=new myTestClass();
myOne.child.child=new myTestClass();
myOne.child.child.child=new myTestClass();
I don't know how much childs there are, yet I want to free all the
memory.
Main question :
how can I do that ?
can I do it by : myOne=null;
should I free every instance ?
I tried it with a loop, first adding all childs to an array (if I
set the 'parent'
to 'null', I can't see what's in it anymore)
var emptyList=new Array();
var tmp=myOne;
while (tmp) {
emptyList.push(tmp);
tmp=tmp.child;
}
for (var i=0; i<emptyList.length; i++) {
emptyList[i]=null;
}
This doesn't work: the 'reference' to the instance in 'emptyList[n]'
is a copy, not a
'reference' so I just use more memory and then empty it again, yet I
don't free the
tree I've made in 'myOne'. (so far as I tested)
can I destroy it from within 'myOne' (with a destory function or
something like that)
(I tried this=null in the class but that doesn't work ;))
Thanx.
Kind regards,
mtjs
