I think that the trObj method of XMLObjectOutput.as has as problem
where it keeps doubling the size of its internal __stack variable
with each new object it has.
The section which has:
// verify that we have not already seen this object
if(obj instanceof Array || obj instanceof Function || obj
instanceof MovieClip || obj instanceof Object)
{
var len = __stack.length;
// walk the stack and look for matches
for(var i = 0; i < len; i++)
{
if(obj == this || __stack[i] == obj)
{
// we have a match, get out
var nSpace = " " + spacer;
trace(spacer + " [self reference - will not
trace]");
return;
} else {
// not found, add it to the list
__stack.push(obj);
}
}
}
seems like it would add the object to the stack each time it iterates
through the for loop unless the particular object it is searching for
happens to be the one it is testing in that iteration. This seems to
be the cause of the problem where the __stack array grows
geometrically in size.
If you're using this to trace objects with any depth, __stack.length
very quickly gets up in to the thousands, self reference or not.
Changing that section of code to:
// verify that we have not already seen this object
if(obj instanceof Array || obj instanceof Function || obj
instanceof MovieClip || obj instanceof Object)
{
var len = __stack.length;
// walk the stack and look for matches
for(var i = 0; i < len; i++)
{
if(obj == this || __stack[i] == obj)
{
// we have a match, get out
var nSpace = " " + spacer;
trace(spacer + " [self reference - will not
trace]");
return;
}
}
// not found, add it to the list
__stack.push(obj);
}
seems to do the trick, although I wonder if there is a way to do this
with hash tables instead of iterating through a numbered array?
Is there a way of generating hash codes or using an object reference
as a key?
