RE: [PHP-DEV] Class Properties in Interfaces?

It might be bad design, but design is down to the application developer and not the people who define a language. I'm not necessary asking for the feature, I just want to understand why we can't do it.

I would start by saying it's bad design. you should use getters and setters which you can define in you interface -- /James On Tue, Apr 29, 2008 at 11:07 AM, John Carter -X (johncart - PolicyApp Ltd at Cisco) <johncart@cisco.com> wrote: Marcus, I understand why Interfaces can't have bodies, but could you explain why Interfaces can't have properties?

Hello Jeremy, interfaces cannot have properties, nor can they have method bodies - that is the whole purpose of interfafces. We are thinking of adding traits which would allow for both but would treat inheritance differently. Until we get that you would need to provide an abstract interface to access data in the same way. marcus Tuesday, April 29, 2008, 5:31:33 AM, you wrote: > Hey list, > I was curious what everyone thought of implementing the ability to > specify class members in interfaces.
