Req #75082 [NEW]: Add interface for SplObjectStorage and use that instead bounding to the class

From: adaliszk at gmail dot com Operating system: Irrelevant PHP version: 7.1.8 Package: SPL related Bug Type: Feature/Change Request Bug description:Add interface for SplObjectStorage and use that instead bounding to the class Description: ------------ So basically if I build my datastructures using SplObjectStorage logic I cannot define properly an interface for my each collection and force usage of a subtype for each of the attach/detach and add/remove methods. For example I want to build a ProductCollection which expect working with only the same type when adding and removing and also has a boundary to only accept ProductEntity I cannot define the interface properly since the SplObjectStorage is bound to itself not to an interface. Sure you can do it with abstract classes and define this boundaries but then each of your collection abstractions would be separated from your other interfaces and you loose polymorphic dependencies or you need to drop your architecture and care this differently. This change should not provide any BC issues, since it's just add interface around the ObjectStorage but it will allow polymorphic interfaces and more tools to design your architecture without implementing code. -- Edit bug report at https://bugs.php.net/bug.php?id=75082&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75082&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75082&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75082&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75082&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75082&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75082&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75082&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75082&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75082&r=support Expected behavior: https://bugs.php.net/fix.php?id=75082&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75082&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75082&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75082&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75082&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75082&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75082&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75082&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75082&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75082&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75082&r=mysqlcfg
