#34924 [NEW]: Decorator pattern - php implementation

From: axo at axolander dot de Operating system: UNIX PHP version: 5.0.5 PHP Bug Type: Class/Object related Bug description: Decorator pattern - php implementation Description: ------------ i'm often making heavy use of the decorator pattern. while this works in c++ or java, php tells me the 'protected' context does not work. how's this to interpret? Reproduce code: --------------- <?php abstract class A { protected abstract function func(); } class Decorator extends A { private $_decorated; public function __construct(A $a) { $this -> _decorated = $a; } protected function func() { $this -> _decorated -> func(); } public function doCall() { $this -> func(); } } class ASmall extends A { protected function func() { printf("%s::%s called!\n",__CLASS__,__FUNCTION__); } } $a = new ASmall(); $dec = new Decorator($a); $dec -> doCall(); die(); Expected result: ---------------- ASmall::func called! Actual result: -------------- <br /> <b>Fatal error</b>: Call to protected method ASmall::func() from context 'Decorator' in <b>fileName</b> on line <b>12</b><br /> -- Edit bug report at http://bugs.php.net/?id=34924&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=34924&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=34924&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=34924&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=34924&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=34924&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=34924&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=34924&r=needscript Try newer version: http://bugs.php.net/fix.php?id=34924&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=34924&r=support Expected behavior: http://bugs.php.net/fix.php?id=34924&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=34924&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=34924&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=34924&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=34924&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=34924&r=dst IIS Stability: http://bugs.php.net/fix.php?id=34924&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=34924&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=34924&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=34924&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=34924&r=mysqlcfg
