MVC Framework/Update
The most important simplifications comparing tslib_pibase.
Links
The dozends of mystical linkfunctions have been replaced with one link object, that has a rather simple API.
class variables
The setting of most class variables of tslib_pibase have been made obsolete.
var $prefixId = 'tx_test_pi1';
Replaced by the function getDesignator(). Without setting it defaults to the extension key.
var $scriptRelPath = 'pi1/class.tx_test_pi1.php';
We have the function includeExtensionFile($relativePath) to include extension files that are no classes. Classes are autoincluded during instantiation by tx_div::makeInstance('className') .
var $extKey = 'test';
Autodetaction by getExtensionKey().
var $this->pi_USER_INT_obj=1;
Has been a heavily confusing misconception of tslib_pibase. It has never been fixed. I suggested solutions.
var $conf;
Configuration works with the configuration object now, that is generated by tx_lib_controller. We just need to call getConfiguration($key).
