[TYPO3-dev] questions about XCLASS replacement in TYPO3 6.2

[Franz Holzinger]

Hello,

during the usage of the replacement for XCLASSing in TYPO3 6.2 and 
reading of the manuals, some questions appeared to me:


1.) Why do you call the usage of 
"$GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects'] " still XCLASS? It should 
be called "using System Objects" or similar. Since TYPO3 6.2 the name 
XCLASS should disappear from the manuals.

2.) What must be done if the array 
$GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects']['TYPO3\CMS\Backend\Controller\NewRecordController'] 
already exists? Shall it be overwritten without any notice? Or is there 
any recommendation for an entry into an error log file?

3.) I cannot get System Objects class extending working with an abstract 
class.
"abstract class AbstractConditionMatcher extends 
\TYPO3\CMS\Core\Configuration\TypoScript\ConditionMatching\AbstractConditionMatcher 
{"
Are abstract classes not supported for extending them?
