Expose PropertyHydrationDefinition to PropertyCaster::cast() to access inferred type
I've got a model, that uses several VO properties, using a ValueObjectInterface.
Trying to create a generic PropertyCaster, CastToValueObjectInterface, I miss the concrete Attribute target (the property on whom is applied) to hydrate the property without need to explicity add the class to be hydrated on the attribute
class Name implements ValueObject {
public function from(mixed $value): self
}
final readonly class Model {
#[CastAsValueObject]
public Name $name
}
readonly class CastToValueObjectInterface implements PropertyCaster {
public function cast(mixed $value, ObjectMapper $hydrator, PropertyHydrationDefinition $context=null): mixed
{
if (!$context?->firstTypeName instanceOf ValueObject)
throw \InvalidArgumentException("Annotated property does not implement ValueObject");
return ($context->firstTypeName)::from($value);
}
}
I'd go so far as to suggest the Caster shouldn't be necessary. The Hydrator should just figure out it's a value object (contructor with single parameter?) and create it.
