Previous Comments: ------------------------------------------------------------------------ [2014-03-25 16:13:29] eldmannen+php at gmail dot com Levim, no it is not. Maybe the person implementing the interface haven't written that method yet. Not all methods in a interface is widely used, some is rarely used. Maybe some implementations would be very tricky to write, so until further it throw NotImplemented. Maybe for some reason it is not feasible to support that method given some circumstances and limitations. NotImplemented is sane and it is supported in multiple other languages and for a good reason. Having to write your own seems silly, as its not project-specific, and hence something that would be much re-used and benefit everyone. ------------------------------------------------------------------------ [2014-03-25 13:47:34] levim@php.net Just make your own and throw it. I'm in favor of revamping the SPL structures and exceptions but even then I wouldn't include NotImplementedException; it's a sign that your interface or parent class isn't designed properly. ------------------------------------------------------------------------ [2014-03-09 17:09:45] eldmannen+php at gmail dot com RuntimeException can be pretty much anything. It is very disambigous. While NotImplementedException is very specific and explicitly conveys that this method is not implemented. If you get a RuntimeException you have no idea what is going on or why you're getting it. If you get a NotImplementedException then you know exactly why you got it. It is also available in many other languages; Python - http://docs.python.org/2/library/exceptions.html#exceptions.NotImplementedError Ruby - http://www.ruby-doc.org/core-1.9.3/NotImplementedError.html .NET Framework - http://msdn.microsoft.com/en-us/library/system.notimplementedexception%28v=vs.110%29.aspx Java - http://docs.oracle.com/javase/7/docs/api/java/lang/UnsupportedOperationException.html ------------------------------------------------------------------------ [2014-03-09 16:43:55] phpmpan at mpan dot pl What's the purpose of such exception? What's its advantage over pure \RuntimeException? ------------------------------------------------------------------------ [2014-03-08 18:00:17] eldmannen+php at gmail dot com Description: ------------ There is no NotImplementedException. Please add a NotImplementedException. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66855&edit=1
