Re: error trapping
In article <2aDHJHA9skD4EwHl@m...>, A. G. McDowell <mcdowella@m...> writes > >The suggested alternative to resumption makes most sense in the context >of resource acquisition. Sacrificing rigor for brevity: >while((resource = acquire()) != null) callback(); >The callback should either release some more resource or throw a >(terminating) exception, so you exit the loop either normally, with the >resource, or via the exception. > but meant while((resource = acquire()) == null) callback(); assuming that acquire() returns null when it fails to get the resource, so that is when we need to callback and retry.
