Installation
------------

[](#installation)

```
composer require brezgalov/php-typed-collection dev-master

```

Description
-----------

[](#description)

Abstraction designed to make typed collections based on **Iterator** interface

If you need more functions - feel fre to add them to your custom implementation. You can implement ArrayAccess when it required

Usage
-----

[](#usage)

```
class MyClassCollection extends AbstractTypedIterator
{
    /**
     * override to set collection element type
     */
    public function current(): MyClass
    {
        return parent::current();
    }

    /**
     * Make shure items are same type
     */
    protected function validateItem($item): bool
    {
        return $item instanceof MyClass;
    }
}

// now go use

$collection = new MyClassCollection([
    new MyClass(),
    new MyClass(),
    new MyClass(),
]);

foreach($collection as $class) {
    // $class instance of MyClass - put your handle logic here
}

```

Deep cloning
------------

[](#deep-cloning)

Objects stored inside collection are references.

If you want to clone collection safely - consider using **ContainerDeepCloneTrait** or **AbstractTypedCloneSafeIterator** as it shown below:

**ContainerDeepCloneTrait**:

```
class MyClassCollection extends AbstractTypedIterator
{
    use ContainerDeepCloneTrait;

    public function current(): MyClass
    {
        return parent::current();
    }

    protected function validateItem($item): bool
    {
        return $item instanceof MyClass;
    }
}

$clone = clone $myClassCollection; // it's deep cloned now

```

**AbstractTypedCloneSafeIterator**:

```
class MyClassCollection extends AbstractTypedCloneSafeIterator
{
    ...
}

function testClone() {
    $myClass = new MyClass();
    $array = [$myClass];

    return new MyClassCollection($array); // $myClass is cloned
}

```
