README

Provides a simple implementation of the Command bus pattern.

Install

composer require awd-studio/command-bus

Usage

• Implement a \AwdStudio\CommandBus\Handler\HandlersCollection (or use a defined one - \AwdStudio\CommandBus\Simple\ArrayCollection)
• Register there all off handlers (must implement AwdStudio\CommandBus\Handler\CommandHandler interface)
• And then - you'll be able to use the bus (AwdStudio\CommandBus\CommandBus):

<?php

use \AwdStudio\CommandBus\CommandBus;
use \AwdStudio\CommandBus\Simple\ArrayCollection;

// Creating the handlers collection
$handlers = new ArrayCollection();

// Fill it with handlers
$handlers->add(new MyCommandAHandler());
$handlers->add(new MyCommandBHandler());

// Remove handlers, if it's required
$handlers->remove(new MyCommandCHandler());

// Creating the bus
$bus = new CommandBus($handlers);

// Handle commands
$bus->handle(new MyCommandA());
$bus->handle(new MyCommandB());
