WP EventEmitter
===============

[](#wp-eventemitter)

An object oriented event emitter for WordPress actions

Motivation
----------

[](#motivation)

A familiar event interface that delegates to the global `add_action` and `do_action` functions of WordPress. It also presents a much more testable interface as it only uses the WP functions if they are available.

Methods
-------

[](#methods)

### on

[](#on)

Delegate to WordPress' [add\_action](https://codex.wordpress.org/Function_Reference/add_action) function. In test environments a local collection of listeners will be used.

### emit

[](#emit)

Delegate to WordPress' [do\_action](https://codex.wordpress.org/Function_Reference/do_action) function. In test environments a local collection of listeners will be used.

### filter

[](#filter)

Delegate to WordPress' [add\_filter](https://codex.wordpress.org/Function_Reference/add_filter) function. In test environments a local collection of listeners will be used.

### applyFilters

[](#applyfilters)

Delegate to WordPress' [apply\_filters](https://codex.wordpress.org/Function_Reference/apply_filters) function. In test environments a local collection of listeners will be used.

Tests
-----

[](#tests)

Tests use PHPUnit

```
$ vendor/bin/phpunit

```
