Ace::Model(3pm)

💖 Ace::Model(3pm) — User Contributed Perl Documentation 💖

okay bestie, quick vibe check: this is the manual page for Ace::Model, part of the Ace Perl library. It's giving "let me tell you everything about AceDB class models" energy, and honestly? iconic. 🎀

---

✨ NAME ✨

Ace::Model — get all the tea on AceDB models. ☕

---

🌸 SYNOPSIS 🌸

use Ace;
my $db = Ace->connect(-path=>'/usr/local/acedb/elegans');
my $model = $db->model('Author');
print $model;
$name = $model->name;
@tags = $model->tags;
print "Paper is a valid tag" if $model->valid_tag('Paper');

That's the whole flex. connect, grab the model, print it, ask for its name, ask for its tags, check if a tag is valid. periodt. 💅

---

🦋 DESCRIPTION 🦋

So basically, this class is your backstage pass to AceDB class models. It hands you the model in a human-readable format, and does some limited-but-actually-useful parsing on your behalf. lowkey helpful, highkey slay. ✨

Wondering how you even get an Ace::Model object? Two ways, bestie:

• Call the model() method on an Ace database handle, and it'll retrieve the model for a named class. 🗂️
• Call the model() method on an Ace::Object, and it'll retrieve that object's particular model. 🎯

Either way, you're in. 🫶

👑 METHODS 👑

🌈 new()

$model = Ace::Model->new($model_data);

This is a constructor, but hear me out — it's intended only for use by the Ace and Ace::Object classes. It builds a brand new Ace::Model object from the raw string data in models.wrm. No cap. 📂

💜 name()

$name = $model->name;

Returns the class name for the model. Simple. Elegant. Main character energy. 👑

🍓 tags()

@tags = $model->tags;

Returns a list of all the valid tags in the model. All of them. Not some, not a few. Every single one. ✨

🧚 valid_tag()

$boolean  = $model->valid_tag($tag);

Returns true if the given tag is part of the model. That's it. That's the method. 💖

🌈 path()

@path = $model->path($tag)

Returns the path to the indicated tag, giving you back a list of intermediate tags. For example — and I'm quoting the lore here — in the C elegans ?Locus model, the path for 'Compelementation_data" will return the list ('Type','Gene'). 🦋

⭐ asString()

print $model->asString;

asString() returns the human-readable representation of the model, with comments stripped out. Internally, this method gets called to automatically convert the model into a string when appropriate. Like, you don't even have to ask — the moment you start doing string operations on the model object, it converts itself into a string automatically. it's giving automatic. 🤖

Example time, bestie:

print "Paper is unique" if $model=~/Paper ?Paper UNIQUE/;
