Identity-contract

This package propose abstract classes to manage Identities in DDD projects.

Features

Builtin typed identities :

• integer based identities
• string based identities
• uuid based identities

Also:

• instance are readonly
• equality test
• request same identity twice return same object

Usage

Int Identity

final readonly class CarId extends AbstractIntIdentity {}

$id = CarId::from(25);

UUID Identity

use JeckelLab\IdentityContract\AbstractUuidIdentity;

final readonly class UserId extends AbstractUuidIdentity {}

$id = UserId::from("d2fbc6c0-0497-42f1-8ece-8840641b67f0");

// or

$id = UserId::new();

// Generating twice same identity return same object

$id1 = UserId::from("d2fbc6c0-0497-42f1-8ece-8840641b67f0");
$id2 = UserId::from("d2fbc6c0-0497-42f1-8ece-8840641b67f0");

var_dump($id1 === $id2); // true
