Disco DI allows to change instances right after its creation with BeanPostProcessor

Code


<?php

use bitExpert\Disco\Annotations\Bean;
use bitExpert\Disco\Annotations\Configuration;
use bitExpert\Disco\Annotations\BeanPostProcessor;
use bitExpert\Disco\BeanPostProcessor as PostProcessorInterface;
use bitExpert\Disco\AnnotationBeanFactory;

class Foo
{
    public $baz;
    
    public function bar() : string
    {
        return $this->baz . 'Disco dancing';
    }
}

class PostProcessor implements PostProcessorInterface
{
    public function postProcess($bean, $beanName)
    {
        if ($bean instanceOf Foo) {
            $bean->baz = 'No way I\'m ';
        }
    }
}

/**
 * @Configuration
 */
class DiConfig
{
    /**
     * @Bean
     */
     public function foo() : Foo
     {
         return new Foo();
     }
     
    /**
     * @BeanPostProcessor
     */
     public function postProcessor()
     {
         return new PostProcessor();
     }
}

$parameters = [];
$beanFactory = new AnnotationBeanFactory(DiConfig::class, $parameters);

$foo = $beanFactory->get('foo');
echo $foo->bar();

Result

No way I'm Disco dancing
