To declare a vended object, you should first declare a protocol that
contains the methods you want to expose and that defines the methods
behaviors (bycopy, byref, in, out, etc...)
Then, you create a class that conforms to this protocol. You may omit
the bycopy, byref and other modifiers in your class interface.
@protocol MyProtocol
- (onway void)foo:(bycopy NSString *)bar;
@end
@interface VendedObject <MyProtocol>
- (void)foo:(NSString *)bar;
@end
And then, instead of vending your object directly, you may export a
protocol checker. This will prevent unexpected call of methods on your
vended object.
NSProtocolChecker *checker = [[NSProtocolChecker alloc]
initWithTarget:myVendedObject
protocol:@protocol(MyProtocol)];
[[NSConnection defaultConnection] setRootObject:checker];
[checker release];
Note that keywords like bycopy are ignored by the runtime for simple
methods calls and are usefull only when you send messages using a
proxy object, so you can safely call methods with thoses modifier
internaly.

bycopy worked, thank you.
Does this mean though that I need to duplicate all of methods, with
one set for internal commands and one for remote commands?
Thank
