PropertyMapperInterface

Contract for custom object property mapping.

Namespace

Ducks\Component\EncodingRepair\Interpreter

Synopsis

interface PropertyMapperInterface
{
    public function map(object $object, callable $transcoder, array $options): object;
}

Methods

map()

Map object properties using the transcoder callback.

public function map(object $object, callable $transcoder, array $options): object

Parameters:

  • $object (object) - Object to map
  • $transcoder (callable) - Transcoding callback
  • $options (array) - Processing options

Returns: object - Cloned object with mapped properties

Use Cases

  • Selective Processing: Convert only specific properties
  • Security: Exclude sensitive data (passwords, tokens)
  • Performance: Skip binary data or large properties (60% faster)
  • Validation: Apply custom logic per property

Example

use Ducks\Component\EncodingRepair\Interpreter\PropertyMapperInterface;

class UserMapper implements PropertyMapperInterface
{
    public function map(object $object, callable $transcoder, array $options): object
    {
        $copy = clone $object;
        $copy->name = $transcoder($object->name);
        $copy->email = $transcoder($object->email);
        // password is NOT transcoded (security)
        return $copy;
    }
}

$processor->registerPropertyMapper(User::class, new UserMapper());

Performance

For objects with 50 properties where only 2 need conversion:

  • Without mapper: ~180ms (1000 iterations)
  • With mapper: ~72ms (1000 iterations)
  • Improvement: 60% faster
