SilverStripe Event Mediator
===========================

[](#silverstripe-event-mediator)

A SilverStripe event emitter based on the mediator pattern, which can be applied to run a bit of code before or after any class method (i.e. triggered) using Silverstripe's [Aspects](https://docs.silverstripe.org/en/3.4/developer_guides/extending/aspects/)

Requirements
------------

[](#requirements)

```
"silverstripe/framework": "3.*"
"composer"

```

Installation
------------

[](#installation)

To install, run below from root of SilverStripe installation:

```
> composer require fspringveldt/silverstripe-event-mediator
```

http://**your-site-url**?flush=1 once composer is complete the flush the manifest.

\##Configuration 1 - Extension based (default) Installing the module adds the `eventMediator\EventExtension` to DataObject. Let's say after each call to `$A->foo()` you'd like to fire off a call to `$B->bar()`, the following added to your composer.yml sets up the events:

```
Injector:
  eventMediator\EventMediator':
    properties:
      events:
        foo:
          triggerBar:
            class: B
            method: bar
```

then in `$A->foo()` do the following:

```
class A{
    function foo(){
        //foo funciton body

        $this->emit(__FUNCTION__);
    }
}
```

\##Configuration 2 - Aspect using AopProxyService Let's say after each call to `$A->foo()` you'd like to fire off a call to `$B->bar()`, the following in your composer.yml should do the trick:

```
Injector:
  'eventMediator\EventMediator':
    properties:
      events:
        foo:
          triggerBar:
            class: B
            method: bar
  ProxiedA:
    class: A
  A:
    class: AopProxyService
    properties:
      proxied: %$ProxiedA
      afterCall:
        foo:
          - %$eventMediator\EventMediator'
```

All parameters from `$A->foo()` are sent through `$B->foo()` for your perusal.
