Clownfish::Hash(3pm)

💖 Clownfish::Hash 💖

okay so bestie, welcome to Clownfish::Hash(3pm) — it's part of the User Contributed Perl Documentation, and it is literally just a hashtable. That's it. That's the whole vibe. ✨

---

🌸 NAME 🌸

Clownfish::Hash — a hashtable. yes queen, that's the name, that's the function, no notes. 💅

---

🦋 SYNOPSIS 🦋

here's the whole thing in three little lines, look how cute it is:

my $hash = Clownfish::Hash->new;
$hash->store($key, $value);
my $value = $hash->fetch($key);

---

🎀 DESCRIPTION 🎀

so the way this works: values get stored by reference, and they can be any kind of Obj. Any. Kind. Go feral, bestie. 🫶

---

✨ CONSTRUCTORS ✨

💜 new

my $hash = Clownfish::Hash->new(
    capacity => $capacity,  # default: 0
);

Returns a brand new Hash. icon behavior fr fr. 👑

• capacity — the number of elements the hash is gonna be asked to hold at the start. (default is 0, so if you don't say anything, she starts empty and unbothered.)

---

🌈 METHODS 🌈

🧚 clear

$hash->clear();

Empties the hash of all key-value pairs. every single one. gone. no crumbs. 💀

🍓 store

$hash->store($key, $value);

Stores a key-value pair. that's it, that's the job. 🌸

⭐ fetch

my $obj = $hash->fetch($key);

Fetches the value that's chillin' with key.

Returns: the value — or undef if key isn't present. so if you get undef back, don't panic, she just doesn't know that key. 😭

🔥 delete

my $obj = $hash->delete($key);

Attempts to delete a key-value pair from the hash. (note the word attempt, bestie — she might not find it.)

Returns: the value, if key exists and the deletion therefore succeeds; otherwise undef. 🫶

💅 has_key

my $bool = $hash->has_key($key);

Tells you whether the key you handed over is present. yes/no, in or out, vibe check complete. ✨

👑 keys

my $arrayref = $hash->keys();

Returns the Hash's keys. an arrayref of them. all of them. 💖

🌸 values

my $arrayref = $hash->values();

Returns the Hash's values. an arrayref, same energy, different list. 🌈

💀 get_size

my $int = $hash->get_size();

Returns the number of key-value pairs. the headcount. the census. the population. 🔥

🧬 INHERITANCE 🧬

Clownfish::Hash isa Clownfish::Obj. she's got lineage, she's got main character energy, she inherited it. 💜

and that's the whole page bestie!! this one came from perl v5.42.3, dated 2026-09-02, and it's the Clownfish::Hash(3pm) page. mwah, go store something. 💖✨🎀🦋
