No, I did not. I didn't even write anything in this thread until a few
minutes ago.
If you are responding to something that a particlar person wrote, then
common sense as well as 2 decades of Usenet customs would suggest to quote
the posting that you are responding to.

I didn't. If you really had read what I posted I asked someone who was
working on the GD project to contact me. There was no question. Please
re-read and try again.

I obviously was not talking to you as you had never posted before. Your
IQ in this matter must not be very high. Otherwise you'd be able to
follow the thread and know it was not directed at you at all. Try again.

Ah the banality of your post. Please post more. First the code I
posted is not the code I'm using. Second, as I've stated time and
again, I did not have any intention of originally posting and then went
"Whatever". If Mr. Unur wanted to look at some EXAMPLE code who am I to
say no. Then he began insulting me. I returned the insults. After
all, I have nothing else better to do than to trade insults with people.
Your problem, along with everyone else, is that I was looking for
help. I was - but only in finding someone - not help with code. I know
how bad Usenet has gotten with people not answering questions and
instead bashing others because they don't conform to that particular
person's outlook on life and coding. That's why I usually avoid Usenet.
I had hoped to just step in, ask for the person I was looking for to get
in touch with me, and then step back out. No such luck I'm afraid. No
- the code Nazi's had to come goosestepping out saying I had to conform.
Sorry - haven't conformed yet and having a great life thank you very much.

years ago and sent in a fix for it too. So have a nice time! Beat each
other up with snide remarks and people bashing. Me? I'm going to go
finish helping the person I've been helping for a while with this

he insulted your code, not you. seems you have major difficulties
separating those two. see a professional therapist to help you overcome
your identity crisis. you are not your code. code posted here is open
for review no matter how or who wrote it. didn't you see the sign on the
door when you came int?

you haven't traded insults with anyone. you have acted like a jerk
defending your bad code. as of conforming, that isn't the
issue. awareness of code quality it. but your blind eye won't see that
so you take code review as a personal insult. bad to be you and worse to
be your code.

well consider your code to be a square peg and there is a round hole in
your head. have fun trying to plug up the hole.

well ok, i ain't so humble! but i do review a lot of perl code. and i
did find a bug in your posted code caused by your poor coding style. you
still haven't seen that and i bet it is causing problems.

Message-Id: <dtu744$7br$1@online.de>
Hi!
I am useing ASP with PERL and would like to write an array into a session
variable. In the Doku I read this should be possible, but I don´t know to
implement it.
This line:
$Session->{'MyVariable'} = @array;
writes the number of elements of the array into the session variable.
How does it work correkt?
Ciao

I thought so, too, when stringification enters the picture they can be equal
only when their types and addresses are exactly the same. But still, hmm,
you cannot have references to two different types pointing to the same
memory address, of course, so on second thought the address is a unique key
alone.
> The strings that are compared may not be the same each time.
Is this because of possible garbage collection, or scalars growing or
shrinking automagically? Hmm speaking of hash keys, my understanding based
on some other languages is that they must depend on the object's state to be
able to work consistantly. But if you use a stringified memory address and
the address changes later on independent of the blessed thing's state, you
cannot just dereference the same blessed thingy to reuse it as a key in
indexing. Many other languages let you freely use objects or whatever else
you like as hash keys. ARe there any workarounds for Perl? One possibility
that came to mind would be to use Data::Dumper and compute a hash value
based on the object's state. Can I somehow access Perl's internal hashing
function for keys to hash my own data, similar to Java's hashCode method?
I do realize Perl is not the same as Java, far from it. Still browsing the
docs for the hashCode method for the Object class, I noticed this contract
for hashing which might be widely applicable. Quoting JDK 5.0:
- Whenever it is invoked on the same object more than once during an
execution of a Java application, the hashCode method must consistently
return the same integer, provided no information used in equals comparisons
on the object is modified. This integer need not remain consistent from one
execution of an application to another execution of the same application.
Interesting, so the internal state may change and you're allowed to return
the same hash code as long as the equality of the object, as far as the user
goes, is not altered. Maybe my suggestion about simply dumping the blessed
thingy's internals isn't wise after all.
- If two objects are equal according to the equals(Object) method, then
calling the hashCode method on each of the two objects must produce the same
integer result.
- It is not required that if two objects are unequal according to the
equals(java.lang.Object) method, then calling the hashCode method on each of
the two objects must produce distinct integer results. However, the
programmer should be aware that producing distinct integer results for
unequal objects may improve the performance of hashtables.
Hmmm don't these last two statements contradict each other? At least on an
initial read, the first seems to say that if two objects of the same Class
return the same boolean for equals, you must return the same hash codes.
However, the second one effectively mitigates the first by saying that if
they produce different boolean values for equals, they don't have to produce
different hashcodes. So as far as I can see, you cannot tell based on the
hash code whether two objects are equal. The hash codes can be the same if
they are and they can still be the same if they aren't. What's the use of
being able to use objects as hash keys then? Perhaps I'm again missing
something fundamental here.

Just blessing has an effect on stringification, even without overloading.
Thus, through hash key stringification
$hash{ $ref} = 1;
bless $ref, 'gaga';
$hash{ $ref};
will access an undefined value unless $ref was blessed into "gaga" to
begin with.
It is true that a string comparison of two references is true if and only
if the references are the same. The strings that are compared may not be
the same each time.
