Net::A...l::Base(3pm)

🦋 Net::AMQP::Protocol::Base — the glow-up page (perl 3pm, bestie) 🦋

okay so real talk, this is Net::AMQP::Protocol::Base, and it's the base class of all the auto-generated protocol classes. yes, the whole little nepo-baby family of protocol classes has a common ancestor and this is her. main character energy fr 💅

✨ NAME ✨

Net::AMQP::Protocol::Base — the base class of auto-generated protocol classes. she's the blueprint, the blueprint-slash-mother-hen, the "everybody gets their traits from me" icon 👑

---

🌸 DESCRIPTION 🌸

okay so how do these subclasses even get born? head over to "load_xml_spec" in Net::AMQP::Protocol — that's the whole auto-generation situation, that's where the magic happens. this page is not the origin story, it's just the family tree. iykyk 🧚

💖 CLASS METHODS 💖

these are the class-level vibes. let's go through them one by one, no skips, we don't skip in this house 🫶

⭐ class_id

the class id straight from the specficiation. yes, that's how it's spelled in the original and i'm keeping it, character for character, don't @ me 💀

🔥 method_id

the method id from the specification. BUT — plot twist — in the case of a content <class> (think Basic, File or Stream), method_id is 0 for the virtual ContentHeader method. that's the whole trick: it lets you create a Header frame in much the same way you create a Method frame, except the method is the virtual ContentHeader. iconic behaviour honestly.

for example:

my $header_frame = Net::AMQP::Protocol::Basic::ContentHeader->new(
  content_type => 'text/html'
);

print $header_frame->method_id(); # prints '0'

look at that 0 printing. slay. ✨

🎀 frame_arguments

contains an ordered arrayref of the fields that make up a frame for this method. order matters bestie, it's giving very "seating chart at the wedding" energy. example:

Net::AMQP::Protocol::Channel::Open->frame_arguments([
    out_of_band => 'short_string'
]);

this is what the Net::AMQP::Frame subclasses use to (de)serialize raw binary data. and plot twist number two: each of these fields is also an accessor for the class objects. multi-hyphenate 💅

🌈 class_spec

contains the hashref that the load_xml_spec() call generated for this class. it's the receipts, basically.

💜 method_spec

same as above, but for this method. yes bestie, it's the method's own little hashref. periodt.

---

🦋 OBJECT METHODS 🦋

🌸 frame_wrap

returns a Net::AMQP::Frame subclass object that wraps the given object, if possible. note the "if possible" — we're not promising anything, we're just being honest about our capabilities 🙈

💀 POD ERRORS 💀

not me having to tell you this but — hey! the above document had some coding errors, and they're explained below:

Around line 61:

=back without =over

that's it, that's the error. a whole =back with no =over to back. we've all been there honestly 😭

and that's the page, bestie!! this was perl v5.42.0, dated 2016-11-28 — yes, she's been around a minute, but she's still serving looks. mwah 💋✨
