The view class is
\XLite\View\Menu\Customer\Top, but modules can "decorate" it by extending their classes from this class and implemeting the IDecorator interface as
follows:
PHP Code:
<?php
namespace XLite\Module\CDev\SimpleCMS\View\Menu\Customer;
class Top extends \XLite\View\Menu\Customer\Top implements \XLite\Base\IDecorator
{
// ...
}
To find every class that affects the base class you should search the source code for "extends BASE_CLASS" string like in the above example.
