TYPO3 Core

// Check whether class is available and try to reload includeLibs if possible:

if ($this->isClassAvailable($cls, $conf)) {

/**

* Checks whether a PHP class is available. If the check fails, the method tries to

* determine the correct includeLibs to make the class available automatically.

*

* TypoScript example that can cause this:

* | plugin.tx_myext_pi1 = USER

* | plugin.tx_myext_pi1 {

* | includeLibs = EXT:myext/pi1/class.tx_myext_pi1.php

* | userFunc = tx_myext_pi1->main

* | }

* | 10 = USER

* | 10.userFunc = tx_myext_pi1->renderHeader

*

* @param string $className: The name of the PHP class to be checked

* @param array $config: TypoScript configuration (naturally of a USER or COA cObject)

* @return boolean Whether the class is available

* @link http://bugs.typo3.org/view.php?id=9654

* @TODO This method was introduced in TYPO3 4.3 and can be removed if the autoload was integrated
