Componenta Filter
=================

[](#componenta-filter)

Composable filter objects for iterable data and reflection/class discovery.

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

[](#installation)

```
composer require componenta/filter
```

Requirements
------------

[](#requirements)

- PHP 8.4+
- `componenta/arrayable`

Related Packages
----------------

[](#related-packages)

PackageWhy it matters here`componenta/arrayable`Filters can expose their result through `toArray()`.`componenta/class-finder`Uses filters to select discovered classes, attributes, and reflection targets.`componenta/iterator`Can combine filtering with replayable iteration.What It Provides
----------------

[](#what-it-provides)

- `FilterInterface`: iterable filter contract with `accept()` and `toArray()`.
- `AbstractFilter`: base implementation for filtering an iterable source.
- `FilterableInterface` and `Filterable`: immutable filter-chain support.
- Concrete filters for scalars, arrays, strings, class names, reflection objects, files, ranges, callbacks, and composition.

Basic Usage
-----------

[](#basic-usage)

```
use Componenta\Filter\StringFilter;

$filter = new StringFilter(['one', 2, 'three']);

$filter->toArray(); // ['one', 'three']
```

Keys are not preserved by default:

```
$filter->toArray(preserveKeys: true);
```

Custom Criteria
---------------

[](#custom-criteria)

```
use Componenta\Filter\CallbackFilter;

$filter = new CallbackFilter(
    static fn(mixed $value, string|int|null $key): bool => is_int($value) && $value > 10,
    [5, 15, 20],
);

$filter->toArray(); // [15, 20]
```

Filter Chains
-------------

[](#filter-chains)

Objects using `Filterable` should return new instances when filters are added or removed.

```
$next = $filterable->withFilter($filter);
$sameWithout = $next->withoutFilter($filter);
```

`accept()` uses AND semantics: every registered filter must accept the value.
