## Codeception\Util\Autoload



Autoloader, which is fully compatible with PSR-4,
and can be used to autoload your `Helper`, `Page`, and `Step` classes.


### addNamespace 

*static*

Adds a base directory for a namespace prefix.

Example:

```php
<?php
// app\Codeception\UserHelper will be loaded from '/path/to/helpers/UserHelper.php'
Autoload::addNamespace('app\Codeception', '/path/to/helpers');

// LoginPage will be loaded from '/path/to/pageobjects/LoginPage.php'
Autoload::addNamespace('', '/path/to/pageobjects');

Autoload::addNamespace('app\Codeception', '/path/to/controllers');
?>
```

 * `param string` $prefix The namespace prefix.
 * `param string` $base_dir A base directory for class files in the namespace.
 * `param bool` $prepend If true, prepend the base directory to the stack instead of appending it;
                     this causes it to be searched first rather than last.
 * `return`  void
