Flow is a business flow implementation.

Why?
----

[](#why)

Often, we are faced with complex business rules. It can be easily verified if the processes and transitions can be visualized. Flow does that and more.

Features
--------

[](#features)

- [Transition Events](https://github.com/xu-li/flow/blob/master/examples/01-events/index.php)
- Visualization - Using [symfony/workflow](https://symfony.com/doc/current/workflow/dumping-workflows.html)

Core classes/interfaces
-----------------------

[](#core-classesinterfaces)

### ProcessInterface

[](#processinterface)

Each process must implement `ProcessInterface`. Each process implementation should avoid storing state. The output of the `proceed()` method should only depend on the input `payload`.

### StrategyInterface

[](#strategyinterface)

A `StrategyInterface` implementation decides which process from a number of possible processes should be picked.

### Flow

[](#flow-1)

The main Flow class. See [Examples](#examples).

Examples
--------

[](#examples)

1. [Simple](https://github.com/xu-li/flow/blob/master/examples/00-simple/index.php)
2. [Listen to transition events](https://github.com/xu-li/flow/blob/master/examples/01-events/index.php)
