[TYPO3-dev] Hook problem

[Tapio Markula]

Hi

I don't understand how to use this kind of hook

$this->hookObjectsMainFields = array();
		if (is_array 
($TYPO3_CONF_VARS['SC_OPTIONS']['t3lib/class.t3lib_tceforms.php']['getMainFieldsClass'])) 
{
			foreach 
($TYPO3_CONF_VARS['SC_OPTIONS']['t3lib/class.t3lib_tceforms.php']['getMainFieldsClass'] 
as $classRef)	{
				$this->hookObjectsMainFields[] = &t3lib_div::getUserObj($classRef);
			}
		}

...

and in another function

	// Hook: getMainFields_preProcess (requested by Thomas Hempel for use 
with the "dynaflex" extension)
		foreach ($this->hookObjectsMainFields as $hookObj)	{
			if (method_exists($hookObj,'getMainFields_preProcess'))	{
				$hookObj->getMainFields_preProcess($table,$row,$this);
			}
		}

in
class.t3lib_tceforms.php


I have used hooks like
$TYPO3_CONF_VARS['EXTCONF'][TM_CONTENTACCESS_EXTkey]['recordAccess'][]='EXT:tm_contentaccess/class.tx_ux_tm_contentaccess.php:tx_ux_tm_contentaccess';
where 'recordAccess' is the name of the function

How to define key definition for
$TYPO3_CONF_VARS['SC_OPTIONS']['t3lib/class.t3lib_tceforms.php']['getMainFieldsClass']
