ReflectionObject instead of Object

[MlleDelphine]

Hi !

I would like to use callback but it seems that there's an issue.
I am using Symfony 3.1.10.

MyEntityObject.php

/**
     * @var string
     *
     * @ORM\Column(name="masterNumber", type="string", length=255, unique=true)
     * @Generate(generator="string", options={"length"=26}, callbacks={"setPrefix"="getPrefix"})
     * @JMSSer\Expose
     * @JMSSer\Groups({"bo_export_masterservicerequest", "crm"})
     */
    private $masterNumber;

  public function getPrefix(){
        $concat = "my logic";
        return $concat;
    }

But, in GeneratorListener.php existence of method getPrefix (in callbacks annotation) is checked on the ReflectionObject of entity and obviously "getPrefix()" method does not exist in ReflectionObject class but methods of ReflectedObject (MyEntityObject) are available thanks to ReflectionObject->getMethods(). and callable thanks to, for each method contained, $method->invoke($myEntityObject, 'argument');

 /**
     * @param GeneratorInterface $generator
     * @param GeneratorAnnotation $annotation
     * @param \ReflectionObject $object
     */
    public function performCallbacks(GeneratorInterface $generator, GeneratorAnnotation $annotation, $object)
    {
        foreach($annotation->callbacks as $callback => $value){

            if($this->isMethod($generator, $callback)){

                if($this->isMethod($object, $value)){
                    $value = $object->$value();
                }
        [...]
            }
        }
    }

    /**
     * @param $class
     * @param $callback
     * @return bool
     */
    private function isMethod($class, $callback)
    {
        return method_exists($class, $callback) && is_callable([$class, $callback]);
    }
