Does Objective-J have protocols like Objective-C?

[jbrennan]

I can't seem to find a language spec for Objective-J and my blind
attempts to use @protocol have not been successful.

Are they supported by the language? Is there a language spec I can
look at?

Thanks,

Jason Brennan.

They are not supported, no. There is no formal specification. The
tutorial on cappuccino.org covers pretty much the entire language
though.

Is there some analog to -repondsToSelector: I can be using to check
which methods a given object implements?

Thanks.

yes. respondsToSelector:

Objective-J is not statically typed. Though you can add type labels,
they are not enforced, at least not currently.
