Headsnet Collections
Installation
composer require headsnet/collections
Usage
Assuming you have some class Foo
that you want to put into a collection:
final class Foo { public function __construct( public string $name ) { } }
Then create a custom named collection to hold the Foo
instances:
/** * @extends AbstractImmutableCollection<Foo> * * @method self filter(callable $func) * @method self reverse() */ final class FooCollection extends AbstractImmutableCollection { public function getItemClassName(): string { return Foo::class; } }
Then instantiate the collection:
$foo1 = new Foo(); $foo2 = new Foo(); $allFoos = new FooCollection([$foo1, $foo2]);
You then have an immutable, iterable object that can be filtered, mapped and walked:
foreach ($allFoos as $foo) { $this->assertInstanceOf(Foo::class, $foo); }
