# Factories

`dot-dependency-injection` is based on 2 reusable factories - `AttributedRepositoryFactory`
and `AttributedServiceFactory` - able to inject any dependency into a class.

## AttributedRepositoryFactory

Injects entity repositories into a class.

### Exceptions thrown

- `Dot\DependencyInjection\Exception\RuntimeException` if repository does not exist
- `Dot\DependencyInjection\Exception\RuntimeException` if repository does not extend `Doctrine\ORM\EntityRepository`
- `Dot\DependencyInjection\Exception\RuntimeException` if repository does not have `#[Entity]` attribute
- `Psr\Container\NotFoundExceptionInterface` if `Doctrine\ORM\EntityManagerInterface` does not exist in the service
  container
- `Psr\Container\ContainerExceptionInterface` if service manager is unable to provide an instance
  of `Doctrine\ORM\EntityManagerInterface`

## AttributedServiceFactory

Injects class dependencies into classes.

If a dependency is specified using the dot notation, `AttributedServiceFactory` will try to load a service having that
specific alias.
If it does not find one, it will try to load the dependency as a config tree, checking each segment if it's available in
the service container.

### Exceptions thrown

- `Dot\DependencyInjection\Exception\RuntimeException` if service does not exist
- `Dot\DependencyInjection\Exception\RuntimeException` if service does not have `#[Inject]` attribute on it's
  constructor
- `Dot\DependencyInjection\Exception\RuntimeException` if service tries to inject itself recursively
- `Psr\Container\NotFoundExceptionInterface` if a dependency does not exist in the service container
- `Psr\Container\ContainerExceptionInterface` if service manager is unable to provide an instance of a dependency
