SimpleTaskFSMBundle

This bundle provides the ability to use FSM tasks runner in your application.

Installation

$ composer require evheniy/simple-task-fsm-bundle "1.*"

Or add to composer.json

"evheniy/simple-task-fsm-bundle": "1.*"

AppKernel:

public function registerBundles()
{
    $bundles = array(
        ...
        new Evheniy\SimpleTaskFSMBundle\SimpleTaskFSMBundle(),
    );
    ...

Documentation

For using SimpleTaskFSMBundle you need to create state classes.

For example AppBundle/FSM/StateInit:

<?php

namespace AppBundle/FSM;

use Evheniy\SimpleTaskFSMBundle\StateAbstract;

class StateInit extends StateAbstract
{

    /**
     * @throw \Evheniy\SimpleTaskFSMBundle\Exception\StateException
     */
    public function run()
    {
        //do something...
    }
}

Then create FSM manager with this state classes (for example in Command):

use Evheniy\SimpleTaskFSMBundle\FSM;

And

$fsm = new FSM(array(new StateInit()));
foreach($fsm as $state) {
    $state->run();
}

OR

$fsm = new FSM(array(new StateInit()));
$fsm->rewind();
while($fsm->valid()) {
    $fsm->current()->run();
    $fsm->next();
}

If you have exception (You can use Evheniy\SimpleTaskFSMBundle\Exception\StateException) and You need to restart step:

$fsm = new FSM(array(new StateWithError()));

$fsm->rewind();
while($fsm->valid()) {
    try {
        $fsm->current()->run();// function run() throws StateException
        $fsm->next();
    } catch (StateException $e) {
        //do something
    }
}

You can use a lot of states and they will run one by one.

$fsm = new FSM(array(new StateInit(), new StateMainTask(), new StateFinish()));
