<?php

use Vehsamrak\ListCollection\TypedList;
use Vehsamrak\ListCollection\IntegerList;

$typedList = new TypedList(Foobar::class, [new Foobar(), new Foobar()]);

$foobar = new Foobar();
$typedList->add($foobar);
$typedList->remove($foobar);

$otherType = new OtherType();
$typedList->add($otherType); // will throw InvalidTypeException

$integerList = new IntegerList();
$integerList->add(1);
$integerList->add('not a number'); // will throw InvalidTypeException

// Examples could be found in `tests` directory

// More use cases can be found in Doctrine collections documentation:
// https://www.doctrine-project.org/projects/doctrine-collections/en/latest/index.html

Creation of custom typed lists

You can create your own typed lists simply by extending TypedList.

<?php
use Vehsamrak\ListCollection\TypedList;

class CustomList extends TypedList
{
    public function __construct(array $elements = [])
    {
        parent::__construct(Custom::class, $elements);
    }
}

Testing

First, install development requirements with composer install. Then, tests could be executed with vendor/bin/phpunit tests
