#Command#

这是一个用于PHP 5.3的简单命令总线

用法

<?php
    namespace Command\Command;

    class MyHandlerCommand
    {
        public $someParam;

        public function __construct($someParam)
        {
            $this->someParam = $someParam;
        }
    }

<?php
    namespace Command\Handler;

    class MyHandlerHandler implements HandlerInterface, ApplicationInterface
    {
        protected $app;
        
        public function handle($object)
        {
            echo $app['db']->persist($object->someParam);
        }
        
        public function setApplication($app)
        {
            $this->app = $app;
        }
    }

    $command = new Command\Command(new Command\Resolver);
    $command->setApplication($app);
    $command->dispatch(new MyHandlerCommand($someParam));

这将解析实现了HandlerInterface接口的MyHandlerHandler，并提供对您的应用程序容器的访问。

自我处理

或者，您可能不想将您的DTO与命令分开。在这种情况下，您可以仅实现自我处理接口，这将调用handle方法。

<?php
namespace Command\Command;
    
class MyHandlerCommand implements SelfHandling
{
    protected $someParam;

    public function __construct($someParam)
    {
        $this->someParam = $someParam;
    }
         
    public function handle()
    {
        return $this->someParam * 2;
    }
}

最后，您可以通过实现ApplicationInterface来获取对应用程序的访问

<?php
class TestCommand implements SelfHandling, ApplicationInterface
{
    private $name;
    private $application;

    public function __construct($name)
    {
        $this->name = $name;
    }

    public function handle()
    {
        $app = $this->application;
        var_dump($app($this->name));
    }

    /**
     * @param $application
     * @return void
     */
    public function setApplication($application)
    {
        $this->application = $application;
    }

}

    $resolver = new \Command\Resolver\SelfHandlingResolver();
    $resolver->setApplication(function($a){ return $a*2;});

    $command = new Command\Command($resolver);
    $command->dispatch(new TestCommand(2));
