Generator Trait
The GeneratorTrait provides an interface to record events and release them at a later time.
Implementation Example
use League\Event\Generator;
class User
{
use Generator;
public function updateAddress(Address $address)
{
$this->address = $address;
$this->addEvent(new UserAddressWasChanged($this, $address));
}
}
$user = new User;
$user->updateAddress(new Address(...));
$events = $user->releaseEvents();
$emitter->emitBatch($events);
When you prefer a more expressive syntax you can alter the addEvent method name like so:
class User
{
use Generator {
addEvent as recordThat;
}
public function updateAddress(Address $address)
{
$this->address = $address;
$this->recordThat(new UserAddressWasChanged($this, $address));
}
}
