Deserialize value of mixed type with JMS Serializer

Question

I have some trouble with JMS Serializer - I need to deserialize a dirty JSON with a mixed type for the score value. For example:

{ label: "hello", score: 50 }

Or

{ label: "hello", score: true }

If I put @Type("int"), when the value is a boolean, it gets deserialized as 1 or 0...
I would like to get 100 when the value is true, and 0 when the value is false.
How could I manage this mixed type on deserialization?

My class:

class Lorem 
{
    /**
     * @Type("string")
     * @SerializedName("label")
     * @var string
     */
    protected $label;

    /**
     * @Type("int")
     * @SerializedName("score")
     * @var int
     */
    protected $score;
}

You can write your custom handler defining a new my_custom_type (or something better named :), which you can then use in your annotations.

Something like this should work:

class MyCustomTypeHandler implements SubscribingHandlerInterface 
{
    /**
     * {@inheritdoc}
     */
    public static function getSubscribingMethods()
    {
        return [
            [
                'direction' => GraphNavigator::DIRECTION_DESERIALIZATION,
                'format' => 'json',
                'type' => 'my_custom_type',
                'method' => 'deserializeFromJSON',
            ],
        ];
    }

    /**
     * The de-serialization function, which will return always an integer.
     *
     * @param JsonDeserializationVisitor $visitor
     * @param int|bool $data
     * @param array $type
     * @return int
     */
    public function deserializeFromJSON(JsonDeserializationVisitor $visitor, $data, array $type)
    {
        if ($data === true) {
            return 100;
        }
        if ($data === false) {
            return 0;
        }
        return $data;
    }
}
