* This is not an NSConnection method, but is a method that may
231

234
* If the delegate implements this method, the NSConnection will
235
* invoke the method for every message request or reply it receives
236
* from the remote NSConnection. The delegate should use the
237
* authentication data to check all the NSData objects
238
* in the components array (ignoring NSPort objects),
239
* and return YES if they are valid, NO otherwise.
242
* If the method returns NO then an
243
* NSFailedAuthentication exception will be raised.
246
* In GNUstep the components array is mutable, allowing
247
* you to replace the NSData objects with your own version.

284
* If the delegate implements this method, it will be called
285
* whenever a new NSConnection is created that has this
286
* NSConnection as its parent. The delegate may take this
287
* opportunity to adjust the configuration of the new
288

289
* parent whether the creation of the new connection is to
290

* The default operation is to return NSDistantObject unless the

* sent bycopy, in which case the actual object is returned.
287
* To force bycopy, an object should return itself.
