note 75961 added to language.oop5.abstract

I don't agree with jfkallens' last comparison between Abstract Classes & Object Interfaces completely. In an Abstract Class, you can define how some methods work, where as in an Object Interface you can not. An Object Interface is essentually nothing but a list of function names that a class must define if the class implements that interface. An Abstract Class is essentually a prototype which hints towards what extending classes should be doing. An Abstract Class can also be thought of as a Base Class that provides some basic functionality, & also defines a built-in Object Interface that all extending classes will implement. So, an Object Interface is really a built-in part of an Abstract Class. ---- Server IP: 69.147.83.197 Probable Submitter: 72.187.245.179 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.abstract.php Edit -- https://master.php.net/note/edit/75961 Del: integrated -- https://master.php.net/note/delete/75961/integrated Del: useless -- https://master.php.net/note/delete/75961/useless Del: bad code -- https://master.php.net/note/delete/75961/bad+code Del: spam -- https://master.php.net/note/delete/75961/spam Del: non-english -- https://master.php.net/note/delete/75961/non-english Del: in docs -- https://master.php.net/note/delete/75961/in+docs Del: other reasons-- https://master.php.net/note/delete/75961 Reject -- https://master.php.net/note/reject/75961 Search -- https://master.php.net/manage/user-notes.php
