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

[](#installation)

```
$ composer require kcs/class-finder
```

Usage
-----

[](#usage)

Finder helps you to discover classes into your project.

The most common way to discover is to use the provided `ComposerFinder`. This will search for classes using the auto-generated class loader from composer and resolving PSR-\* namespaces accordingly.

Read more in the docs at

### Basic usage

[](#basic-usage)

```
use Kcs\ClassFinder\Finder\ComposerFinder;

$finder = new ComposerFinder();
foreach ($finder as $className => $reflector) {
    // Do magic things...
}
```

### Filtering

[](#filtering)

You can filter classes using the methods exposed by `FinderInterface`:

- `implementationOf(array $interfaces)`: Finds the classes that implements all the given interfaces. You can pass a single interface as string.
- `subclassOf(string $superClass)`: Finds all the classes that are subclasses of the given class.
- `annontatedBy(string $annotationClass)`: Finds all the classes that have the given annotation in the class docblock.
- `withAttribute(string $attributeClass)`: Finds all the classes that have the given attribute applied on the class (PHP >= 8.0) only.
- `in(array $dirs)`: Searches only in given directories.
- `inNamespace(array $namespaces)`: Searches only in given namespaces.
- `filter(callable $callback)`: Custom filtering callback.
- `pathFilter(callable $callback)`: Custom filtering callback for loading files.
