Is this how properties are declared behind the scenes?

I was wondering about how the setter methods get created and am I right in saying this:

Retain/Strong attribute:

- (void)setProperty:(Class *)class
{
    variable = [class retain];
}

Assign/Weak attribute:

- (void)setProperty:(Class *)class
{
    variable = class;
}

Copy attribute:

- (void)setProperty:(Class *)class
{
    variable = [class copy];
}

Are assign and weak even the same either?

Thanks in advance!

All are not correct. Google and you will find same sample code of manual creation of setters and getters – Anoop Vaidya Jan 10 '13 at 18:57
Yeah, that's the general idea, but the devil is in the details. With a retained property you need to be sure to release the prior one. And several other minor points in case of concurrency, etc. – Hot Licks Jan 10 '13 at 19:37
