Using the Serializable Event Message

The AbstractSerializableMessage allows you to quickly create Event Messages that are dispatched.

First you will need to create your Event Message Class.

class AggregateFieldChangedEventMessage extends AbstractSerializableMessage
{
}

Initializing Event Message Class

Once you create you Event Message Class, using it is very easy.

<?php
$event = AggregateFieldChangedEventMessage::new()->withPayload([
    'previous_value' => $previousValue,
    'new_value'      => $newValue,
]);
