[ome-devel] async callbacks in blitz 5.4.x

[Manuel Stritt]

Dear all,

I'm wondering what's the correct way to handle async callbacks, e.g.
deleting an object, as a non-async call
(wait until the command has been executed).

The docu for deleting an object:
https://docs.openmicroscopy.org/omero/5.4.0/developers/Java.html#delete-data

calls loop(10,500) to wait until it is finished.
- why do you wait 10 times 500 and not one time 5000 ?
- if the call is finished after a few loops, will it still do the other
waits?
- is there a guaranty that after the loop call the command has been
finished?

My goal is to wait until the call is finished.
What about s.th. like

CmdCallbackI callback = dm.delete(context, object);
while (callback.getResponse()!=null) {
  Thread.sleep(100);
}
?

Thanks for your help!

Regards,
Manuel
