Collection
==========

[](#collection)

This library implements a few helpful collection classes and interfaces.

TypedArray
----------

[](#typedarray)

This class behaves exactly like an array, but only allows items of a specified type:

```
$monkeys = new \Collection\TypedArray(Monkey::class);

$monkeys->add(new Monkey('Bubbles')); // OK
$monkeys[] = new Monkey('King Kong'); // OK
$monkeys->add(new Snake('Kaa')); // throws CollectionException

// You can iterate over the collection
foreach ($monkeys as $monkey) {
    echo $monkey->getName();
}
```

Adding items to a collection
----------------------------

[](#adding-items-to-a-collection)

You can add items in the regular array way:

```
$monkeys[] = new Monkey('King Kong');
```

Or use the `add()` method

```
$monkeys->add(new Monkey('King Kong'));
```

Identifiable interface
----------------------

[](#identifiable-interface)

The `Identifiable` class forces a class to implement the `identifier()` method. This method should return a key that makes this instance of a class unique. Maybe it's an ID, a key, a name, or an email address, as long as it uniquely identifies the item.

```
class Monkey implements \Collection\Identifiable
{
    protected $name;
    public function __construct($name)
    {
        $this->name = $name;
    }

    public function identifier()
    {
        return $this->name;
    }
}
```

When adding instances of this class to a collection, the identifier will automatically be used as the key:

```
$monkeys = new \Collection\TypedArray(Monkey::class);

$m1 = new Monkey('George');
$m2 = new Monkey('Koko');

$monkeys[] = $m1; // array contains 1 item
$monkeys[] = $m2; // array contains 2 item
$monkeys[] = $m2; // array still contains 2 items!
$monkeys->add($m2); // array still contains 2 items!

$monkeys->hasKey('George')); // returns true
$monkeys->hasKey('King Kong')); // returns false
isset($monkeys['George']); // returns true
```

Using collections in classes
----------------------------

[](#using-collections-in-classes)

```
class Zoo
{
    protected $monkeys;

    public function __construct()
    {
        $this->monkeys = new Collection\TypedArray(Monkey::class);
    }

    public function getMonkeys()
    {
        return $this->monkeys;
    }
}

$zoo = new Zoo();
$zoo->getMonkeys()->add(new Monkey('Koko');

foreach ($zoo->getMonkeys() as $monkey() {
}
```
