Hi all, I added another issue, and would welcome comments. Cheers, Andre. 63) should there be a method: task.get_task_factory () which returns the tf which created the task? GridRPC has a similar method call, and it seems to make it much easier to keep track of tasks. E.g. one could start a remote read task, and when that is finished start another read: saga::file f (url); saga::file::task_factory ftf = file.get_task_factory (); saga::task t = ftf.read (100, out); t.run (); ... // do may things if ( saga::task::Done = t.get_status () ) { // ok, do another read on that one... saga::file::task_factory ftf = t.get_task_factory (); ftf.read (100, out2); } That would be VERY useful for task containers, e.g. if 1 of n tasks finishes, and requires a follow up call on the same task factory. Right now, the user needs to maintain a mapping from task to the respective task factory (which is not tooo difficult though, just possibly cumbersome). However: the problem with that approach is, that the return type for the call differs for the various task types!! So it would either require: - have specific task types, and have task container etc. work on a base class of them (ugh?) - have a base task_factory type which gets returned and casted (ugh?) -- +-----------------------------------------------------------------+ | Andre Merzky | phon: +31 - 20 - 598 - 7759 | | Vrije Universiteit Amsterdam (VU) | fax : +31 - 20 - 598 - 7653 | | Dept. of Computer Science | mail: merzky@cs.vu.nl | | De Boelelaan 1083a | www: http://www.merzky.net | | 1081 HV Amsterdam, Netherlands | | +-----------------------------------------------------------------+
