Zonema...RRList(3pm)

✨ NAME ✨

Zonemaster::LDNS::RRList — the class that's literally a whole list of resource records, bestie 💅

It lives in the Zonemaster::LDNS::RRList lane, and it's part of the user-contributed Perl documentation situation, iykyk.

---

🌸 SYNOPSIS 🌸

Okay so here's the vibe, in one line:

my $rrlist = Zonemaster::LDNS::RRList->new( $rrs_aref );

That's it, that's the whole first look. Slay.

🎀 CLASS METHODS 🎀

• new() — makes you a brand-new, squeaky-clean, empty Zonemaster::LDNS::RRList object. It's giving blank canvas, main character origin story, no notes 🦋
• new($rrs) — makes you a Zonemaster::LDNS::RRList object but populated with the resource records you hand over.

It takes a reference to an array of Zonemaster::LDNS::RR objects. So yes, an aref of RRs, that's the whole bit.

And it returns a Zonemaster::LDNS::RRList object back to you. Periodt 💖

👑 INSTANCE METHODS 👑

• count() — tells you how many RRs are chillin' in the list. Just the number, no drama.
• compare($other) — compares two Zonemaster::LDNS::RRList objects. The order of the Zonemaster::LDNS::RR objects inside the list does not matter (she does not care about your lineup, she cares about your content 💅). The TTL field is ignored, and comparing domain names is case insensitive.

It returns an integer, and 0 means they're equal. So if you get 0, that's a good thing here, not a bad thing, don't panic 😭

• get($pos) — retrieves the RR at the position you asked for. Example:

my $rr = Zonemaster::LDNS::RRList->get( 0 );

It takes an integer. It returns a Zonemaster::LDNS::RR object — or undef if there was no RR at that spot. Ghosted by an index, we've all been there 🙈

• push($rr) — pushes an RR onto the list. Adding to the roster, as one does ✨
• pop() — pops an RR off the list. Bye bestie, thanks for coming 🫶
• is_rrset() — returns true or false depending on if the list is an RRset or not.

Heads up bestie, this is important: the underlying LDNS function appears to have a bug, because the comparison of the owner name field is case sensitive. See https://github.com/NLnetLabs/ldns/pull/251 — go look at it, not me guessing, fr fr 💀

• string() — returns a string with the list of RRs in presentation format. Pretty-printed for your viewing pleasure 🌈
• do_compare($other) — calls the XS compare method with the arguments it needs, rather than the ones overloading gives. So it bypasses the overloading shenanigans entirely.
• to_string — calls the XS string method with the arguments it needs, rather than the ones overloading gives. Functionally it's identical to string() from the Perl level, except it's a tiny little bit slower. Yeah. Slower. We said what we said 🧚
