Class

NSDistantObjectRequest

An object used by the distributed objects system to help handle invocations between different processes.

Overview

Do not create NSDistantObjectRequest objects directly. Unless you are getting involved with the low-level details of distributed objects, there should never be a need to access an NSDistantObjectRequest. To intercept and possibly process requests yourself, implement the NSConnection delegate method connection:handleRequest:.
