vlastny datovy typ v properties

zdravim,

nieco som nasiel tu:
https://forum.dibiphp.com/…orm-nad-dibi?p=15
ale moc mi to nepomohlo
mam entiu:

/**

• @property MatchResult $matchResult m:passThru(convertToPoint|)

  */

  class Match extends \LeanMapper\Entity {

  public function convertToPoint($value) {
  return (string) $value;
   }

}

kde MatchResult obsahuje metodu:
public function __toString() {
return sprintf(„POINT(%s, %s)“, $this->player1Score, $this->player2Score);
}

pri citani z property:
$match->matchResult
mam chybu:
LeanMapper\Exception\InvalidValueException: Property ‚matchResult‘ in entity GameModule\Model\Entity\Match is expected to contain an instance of GameModule\Model\Entity\MatchResult, string given.

potrbujem to, aby som mohol ukladat data do typu POINT, takze by mi pomohlo aj ine riesenie.
