Pipeline Iterator Filter
========================

[](#pipeline-iterator-filter)

`PipelineFilterIterator` library provides a flexible and powerful way to filter and manipulate [PHP Iterators](https://www.php.net/manual/en/spl.iterators.php)using a pipeline-based approach. It allows developers to apply multiple filters sequentially in a clean and readable manner.

You can use SPL filters like `CallbackFilterIterator`, `RegexIterator` or create your own filter by extending the [FilterIterator](https://www.php.net/manual/en/class.filteriterator.php) in simple way.

```
class EvenFilter extends FilterIterator
{
    public function accept(): bool
    {
        return $this->current() % 2 === 0;
    }
}
```

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

[](#installation)

```
composer require millancore/pipeline-iterator
```

Usage
-----

[](#usage)

```
use Millancore\PipelineIterator\PipelineFilterIterator;

$arrayData = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

/**
* Use with Iterator
* $iterator = PipelineFilterIterator::create(new ArrayIterator($arrayData))
*/

// Use with Array directly
$iterator = PipelineFilterIterator::createFromArray($arrayData)
    ->filter(EvenFilter::class)
    ->filter(CallbackFilterIterator::class, fn($value) => $value > 3)
    ->filter(RangeFilter::class, 5, 10);

foreach ($iterator as $value) {
    echo $value; // Output: 6, 8, 10
}
```

Filters with arguments
----------------------

[](#filters-with-arguments)

The first arguments MUST BE Iterator

```
class RangeFilter extends FilterIterator
{
    public function __construct(
        Iterator             $iterator,
        private readonly int $start,
        private readonly int $end
    ) {
        parent::__construct($iterator);
    }

    public function accept(): bool
    {
        return $this->current() >= $this->start && $this->current() end;
    }
}
```
