Interface without Attributes and Methods

Sivakumar_Subramaniam — Wed, 10 Dec 2008 11:05:15 GMT

Hi Experts.,

What is the use of having an interface without Attributes and Methods.

I saw the interface IF_MODEL_MM in standard, wondered what would be the purpose of this interface .

Kindly guide me regarding this ..

Thanks & Regards.,

Hello Sivakumar

Such naked interfaces may be used to mark a class for special purpose. For example if you add interface IF_SERIALIZABLE_OBJECT to your class then you can serialize instances of this class.

I am not sure about the function of IF_MODEL_MM but looking at the implementing classes is seems to have an important (yet unknown) function as well.

Regards

Uwe
