Re: Objects and passing/calling methods

When you call

$packObj->createTicket($project);
[download]

the method gets called with only two arguments, $self and $project; there's no class.

"Unitialized value in subroutine entry" means you're calling an XS sub with undef in place of one of its arguments. We need more details to comment on that.

($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord
}map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,

Ah, that explains it then. I was under the assumption that self and class are always passed inherently. So if class is not, what is the class of the ticket object? SomePackage or SomePackage::Ticket?	[reply]

The one it's been blessed to. ($q=q:Sq=~/;[c](.)(.)/;chr(-\|\|-\|5+lengthSq)`"S\|oS2"`map{chr \|+ord }map{substrSq`S_+\|`\|}3E\|-\|`7**2-3:)=~y+S\|`+$1,++print+eval$q,q,a, [download]	[reply] [d/l]

I was under the assumption that self and class are always passed inherently. I can recommend a read of perlobj, which says (among many other useful things): When you call a method, the thing on the left side of the arrow is passed as the first argument to the method. That means when we call `Critter->new()`, the `new()` method receives the string `"Critter"` as its first argument. When we call `$fred->speak()`, the `$fred` variable is passed as the first argument to `speak()`. And BTW, since there was mention of it further down in the thread, having to retrieve the class of one's own object with something like ref would seem like a code smell to me, most things can (and should) be solved with the appropriate OO concepts (encapsulation, inheritance, etc.). But I guess you were asking about the class out of curiosity, not because you need it?	[reply] [d/l] [select]
