Well I want to implement plug-in like mechanism for an application . I
want
to define some minimum functions that any body writing a plugin has to
implement. For that i thought an interface would be best because in a
scenario where the function is not implemented some kind of error would
occur. I would love to hear if you think their is a better way to achieve
this
Well you could define a real default plugin class that actually does
something.
Then anyone who wants to create a plugin can inherit from that and either
extend the default functions or override them with something different.
That will reduce the code that plug-in writers need to create and prevent
any error messages appearing for the user.
It also means the default plug in acts as sample code for the interface
too.
