EventStoreInterface Implementation Guide

Overview

The EventStoreInterface defines a contract for implementing an event store, allowing the storage and retrieval of events related to aggregates.

Interface Methods

storeEvent

This method is responsible for storing an event in the event store. It takes an instance of EventInterface as a parameter.

// Example Implementation
public function storeEvent(EventInterface $event): void
{
    // Your implementation logic to store the event in the event store
}

Parameters

• $event (EventInterface): The event to be stored in the event store.

replyFromPosition

This method retrieves events for a given aggregate starting from a specified position. It returns an Iterator that allows iterating over the retrieved events.

public function replyFromPosition(string $aggregateId, int $position = 0): Iterator;

Parameters

• $aggregateId (string): The identifier of the aggregate for which events are to be retrieved.
• $position (int, optional): The starting position from which to retrieve events. Defaults to 0.
