Details

public bool equals(ObjectIdentityInterface $identity)

We specifically require this method so we can check for object equality explicitly, and do not have to rely on referencial equality instead.

Though in most cases, both checks should result in the same outcome.

Referential Equality: $object1 === $object2 Example for Object Equality: $object1->getId() === $object2->getId()

public string getIdentifier()

Obtains a unique identifier for this object.

The identifier must not be re-used for other objects with the same type.

public string getType()

Returns a type for the domain object.

Typically, this is the PHP class name.
