JLoader::register alternative

[gba]

Hello!

I am using following code to be able to extend the model class 'Manage' of the component com_installer:

Code: Select all

use Joomla\CMS\Version;
$JVer = (new Version)->getShortVersion();
if (version_compare($JVer, '4.0', '>=')) {  // For Joomla!4.0
	JLoader::register('ManageModel', JPATH_ADMINISTRATOR . '/components/com_installer/src/Model/ManageModel.php');
	class_alias('Joomla\Component\Installer\Administrator\Model\ManageModel', 'InstallerModelManage');
} else if (version_compare($JVer, '3.9', '>=')) {  // For Joomla!3.9
	JLoader::register('InstallerModelManage', JPATH_ADMINISTRATOR . '/components/com_installer/models/manage.php');
}

class MycompModelMymodel extends InstallerModelManage
{
	...
}

Is there also another, more advanced way to extend a class of another component, without using JLoader?

Thank you very much in advance for any useful hint!

Kind regards,
Gerald

On J4 you could create an alias for the namespaced class:

Code: Select all

if (version_compare(JVERSION, '4.0', '<'))
{
	JLoader::register('InstallerModelManage', JPATH_ADMINISTRATOR . '/components/com_installer/models/manage.php');
}
else
{
	JLoader::registerAlias('InstallerModelManage', 'Joomla\Component\Installer\Administrator\Model\ManageModel');
}

class MyInstaller extends InstallerModelManage
{

}
